Herin is the code and example data sets for the publication titled:
"Redefining Near-Unity Luminescence in Quantum Dots with Photothermal
Threshold Quantum Yield." The abstract of this paper is as follows. A
variety of optical applications rely on the absorption and reemission of
light. The quantum yield of this process often plays an essential role.
When the quantum yield deviates from unity by significantly less than 1%,
applications such as luminescent concentrators and optical refrigerators
become possible. To evaluate such high performance, we develop a
measurement technique for luminescence efficiency with sufficient accuracy
below 1 part per thousand. Photothermal threshold quantum yield was
developed utilizing the quantization of light to minimize overall
measurement uncertainty. This technique is used to guide a procedure
capable of making ensembles of near-unity emitting CdSe/CdS core/shell
quantum dots. The photothermal threshold quantum yield luminescence
efficiency reaches 0.996 ± 0.002, indicating nearly complete suppression
of nonradiative decay channels.
