Studies about the optimal synthesis conditions were performed, where these organic molecules were converted into C-dots by hydrothermal carbonization at 180 ºC for 18 h. The C-dots exhibited a green emission light at 459 nm when excited under UV-light ( λ ex= 370 nm). These nanomaterials were also successfully used to prepare C-dots/poly (vinyl alcohol) luminescent composites (C-dots/PVA). Both C-dots and C-dots/PVA composite films were investigated by using colorimetric visual sensor for Fe3+ metal ions detection. The results show that the prepared C-dots and C-dots/poly presented strong green emission light. The emission spectra of above materials were quenched in the presence of Fe3+ ions. Thus, highly specific “turn off” fluorescence sensing of Fe3+ was achieved using fluorescent C-dots. Regarding, this work describe that the polymeric films as sensors of metallic ions in aqueous solution appears as a new perspectives to design new composite materials.","descriptionType":"Abstract"}],"geoLocations":[],"fundingReferences":[],"xml":"PD94bWwgdmVyc2lvbj0iMS4wIiBlbmNvZGluZz0iVVRGLTgiPz4KPHJlc291cmNlIHhtbG5zPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCIgeG1sbnM6eHNpPSJodHRwOi8vd3d3LnczLm9yZy8yMDAxL1hNTFNjaGVtYS1pbnN0YW5jZSIgeHNpOnNjaGVtYUxvY2F0aW9uPSJodHRwOi8vZGF0YWNpdGUub3JnL3NjaGVtYS9rZXJuZWwtNCBodHRwOi8vc2NoZW1hLmRhdGFjaXRlLm9yZy9tZXRhL2tlcm5lbC00LjEvbWV0YWRhdGEueHNkIj4KICA8aWRlbnRpZmllciBpZGVudGlmaWVyVHlwZT0iRE9JIj4xMC42MDg0L005LkZJR1NIQVJFLjgyNTk5NDEuVjE8L2lkZW50aWZpZXI+CiAgPGNyZWF0b3JzPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5Kb3N0b24gQ2FydmFsaG88L2NyZWF0b3JOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5MacOpbGlhIFJvZHJpZ3VlcyBTYW50b3M8L2NyZWF0b3JOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5Kb3PDqSBDYXJsb3MgR2VybWlubzwvY3JlYXRvck5hbWU+CiAgICA8L2NyZWF0b3I+CiAgICA8Y3JlYXRvcj4KICAgICAgPGNyZWF0b3JOYW1lPkFpbHRvbiBKb3PDqSBUZXJlem88L2NyZWF0b3JOYW1lPgogICAgPC9jcmVhdG9yPgogICAgPGNyZWF0b3I+CiAgICAgIDxjcmVhdG9yTmFtZT5Kw6lmZXJzb24gQXBhcmVjaWRvIE1vcmV0bzwvY3JlYXRvck5hbWU+CiAgICA8L2NyZWF0b3I+CiAgICA8Y3JlYXRvcj4KICAgICAgPGNyZWF0b3JOYW1lPkZlcm5hbmRvIErDum5pb3IgUXVpdGVzPC9jcmVhdG9yTmFtZT4KICAgIDwvY3JlYXRvcj4KICAgIDxjcmVhdG9yPgogICAgICA8Y3JlYXRvck5hbWU+UmVuYXRvIEdhcmNpYSBGcmVpdGFzPC9jcmVhdG9yTmFtZT4KICAgIDwvY3JlYXRvcj4KICA8L2NyZWF0b3JzPgogIDx0aXRsZXM+CiAgICA8dGl0bGU+SHlkcm90aGVybWFsIFN5bnRoZXNpcyB0byBXYXRlci1zdGFibGUgTHVtaW5lc2NlbnQgQ2FyYm9uIERvdHMgZnJvbSBBY2Vyb2xhIEZydWl0IGZvciBQaG90b2x1bWluZXNjZW50IENvbXBvc2l0ZXMgUHJlcGFyYXRpb24gYW5kIGl0cyBBcHBsaWNhdGlvbiBhcyBTZW5zb3JzPC90aXRsZT4KICA8L3RpdGxlcz4KICA8ZGVzY3JpcHRpb25zPgogICAgPGRlc2NyaXB0aW9uIGRlc2NyaXB0aW9uVHlwZT0iQWJzdHJhY3QiPiZsdDtkaXYmZ3Q7Jmx0O3AmZ3Q7Q2FyYm9uIGRvdHMgKEMtZG90cykgcG9zc2VzcyB0aGUgYXR0cmFjdGl2ZSBwcm9wZXJ0aWVzIG9mIGhpZ2ggc3RhYmlsaXR5LCBsb3cgdG94aWNpdHksIGdvb2Qgd2F0ZXIgc29sdWJpbGl0eSwgc2ltcGxlIHN5bnRoZXRpYyByb3V0ZXMgYXMgd2VsbCBhcyBzaXplIGFuZCBleGNpdGF0aW9uLWRlcGVuZGVudCBwaG90b2x1bWluZXNjZW5jZSAoUEwpLlRoZSBhaW0gb2YgdGhpcyB3b3JrIHdhcyB0byBzeW50aGVzaXplIHBob3RvbHVtaW5lc2NlbnQgQy1kb3RzIGJ5IGh5ZHJvdGhlcm1hbCBtZXRob2QgdXNpbmcgYWNlcm9sYSBmcnVpdCAoTWFscGlnaGlhZW1hcmdpbmF0YSkgYXMgYSByb3cgbWF0ZXJpYWwsIHNpbmNlIHRoaXMgZnJ1aXQgY29udGFpbnMgbGFyZ2UgbnVtYmVyIG9mIG9yZ2FuaWMgbW9sZWN1bGVzLiBTdHVkaWVzIGFib3V0IHRoZSBvcHRpbWFsIHN5bnRoZXNpcyBjb25kaXRpb25zIHdlcmUgcGVyZm9ybWVkLCB3aGVyZSB0aGVzZSBvcmdhbmljIG1vbGVjdWxlcyB3ZXJlIGNvbnZlcnRlZCBpbnRvIEMtZG90cyBieSBoeWRyb3RoZXJtYWwgY2FyYm9uaXphdGlvbiBhdCAxODAgwrpDIGZvciAxOCBoLiBUaGUgQy1kb3RzIGV4aGliaXRlZCBhIGdyZWVuIGVtaXNzaW9uIGxpZ2h0IGF0IDQ1OSBubSB3aGVuIGV4Y2l0ZWQgdW5kZXIgVVYtbGlnaHQgKCDOuyBleD0gMzcwIG5tKS4gVGhlc2UgbmFub21hdGVyaWFscyB3ZXJlIGFsc28gc3VjY2Vzc2Z1bGx5IHVzZWQgdG8gcHJlcGFyZSBDLWRvdHMvcG9seSAodmlueWwgYWxjb2hvbCkgbHVtaW5lc2NlbnQgY29tcG9zaXRlcyAoQy1kb3RzL1BWQSkuIEJvdGggQy1kb3RzIGFuZCBDLWRvdHMvUFZBIGNvbXBvc2l0ZSBmaWxtcyB3ZXJlIGludmVzdGlnYXRlZCBieSB1c2luZyBjb2xvcmltZXRyaWMgdmlzdWFsIHNlbnNvciBmb3IgRmUzKyBtZXRhbCBpb25zIGRldGVjdGlvbi4gVGhlIHJlc3VsdHMgc2hvdyB0aGF0IHRoZSBwcmVwYXJlZCBDLWRvdHMgYW5kIEMtZG90cy9wb2x5IHByZXNlbnRlZCBzdHJvbmcgZ3JlZW4gZW1pc3Npb24gbGlnaHQuIFRoZSBlbWlzc2lvbiBzcGVjdHJhIG9mIGFib3ZlIG1hdGVyaWFscyB3ZXJlIHF1ZW5jaGVkIGluIHRoZSBwcmVzZW5jZSBvZiBGZTMrIGlvbnMuIFRodXMsIGhpZ2hseSBzcGVjaWZpYyDigJx0dXJuIG9mZuKAnSBmbHVvcmVzY2VuY2Ugc2Vuc2luZyBvZiBGZTMrIHdhcyBhY2hpZXZlZCB1c2luZyBmbHVvcmVzY2VudCBDLWRvdHMuIFJlZ2FyZGluZywgdGhpcyB3b3JrIGRlc2NyaWJlIHRoYXQgdGhlIHBvbHltZXJpYyBmaWxtcyBhcyBzZW5zb3JzIG9mIG1ldGFsbGljIGlvbnMgaW4gYXF1ZW91cyBzb2x1dGlvbiBhcHBlYXJzIGFzIGEgbmV3IHBlcnNwZWN0aXZlcyB0byBkZXNpZ24gbmV3IGNvbXBvc2l0ZSBtYXRlcmlhbHMuJmx0Oy9wJmd0OyZsdDsvZGl2Jmd0OzwvZGVzY3JpcHRpb24+CiAgPC9kZXNjcmlwdGlvbnM+CiAgPHN1YmplY3RzPgogICAgPHN1YmplY3Qgc2NoZW1lVVJJPSJodHRwOi8vd3d3LmFicy5nb3YuYXUvYXVzc3RhdHMvYWJzQC5uc2YvMC82QkI0MjdBQjk2OTZDMjI1Q0EyNTc0MTgwMDA0NDYzRSIgc3ViamVjdFNjaGVtZT0iRk9SIj45MDQ5OSBDaGVtaWNhbCBFbmdpbmVlcmluZyBub3QgZWxzZXdoZXJlIGNsYXNzaWZpZWQ8L3N1YmplY3Q+CiAgICA8c3ViamVjdCBzY2hlbWVVUkk9Imh0dHA6Ly93d3cuYWJzLmdvdi5hdS9hdXNzdGF0cy9hYnNALm5zZi8wLzZCQjQyN0FCOTY5NkMyMjVDQTI1NzQxODAwMDQ0NjNFIiBzdWJqZWN0U2NoZW1lPSJGT1IiPjkxMjA3IE1ldGFscyBhbmQgQWxsb3kgTWF0ZXJpYWxzPC9zdWJqZWN0PgogICAgPHN1YmplY3Qgc2NoZW1lVVJJPSJodHRwOi8vd3d3LmFicy5nb3YuYXUvYXVzc3RhdHMvYWJzQC5uc2YvMC82QkI0MjdBQjk2OTZDMjI1Q0EyNTc0MTgwMDA0NDYzRSIgc3ViamVjdFNjaGVtZT0iRk9SIj45MTI5OSBNYXRlcmlhbHMgRW5naW5lZXJpbmcgbm90IGVsc2V3aGVyZSBjbGFzc2lmaWVkPC9zdWJqZWN0PgogIDwvc3ViamVjdHM+CiAgPHB1Ymxpc2hlcj5TY2lFTE8gam91cm5hbHM8L3B1Ymxpc2hlcj4KICA8cHVibGljYXRpb25ZZWFyPjIwMTk8L3B1YmxpY2F0aW9uWWVhcj4KICA8ZGF0ZXM+CiAgICA8ZGF0ZSBkYXRlVHlwZT0iQ3JlYXRlZCI+MjAxOS0wNi0xMjwvZGF0ZT4KICAgIDxkYXRlIGRhdGVUeXBlPSJVcGRhdGVkIj4yMDE5LTA2LTEyPC9kYXRlPgogIDwvZGF0ZXM+CiAgPHJlc291cmNlVHlwZSByZXNvdXJjZVR5cGVHZW5lcmFsPSJEYXRhc2V0Ij5EYXRhc2V0PC9yZXNvdXJjZVR5cGU+CiAgPHNpemVzPgogICAgPHNpemU+MjA0MTE3MCBCeXRlczwvc2l6ZT4KICA8L3NpemVzPgogIDxyZWxhdGVkSWRlbnRpZmllcnM+CiAgICA8cmVsYXRlZElkZW50aWZpZXIgcmVsYXRlZElkZW50aWZpZXJUeXBlPSJET0kiIHJlbGF0aW9uVHlwZT0iSXNTdXBwbGVtZW50VG8iPjEwLjE1OTAvMTk4MC01MzczLW1yLTIwMTgtMDkyM
