Redefining Near-Unity Luminescence in Quantum Dots with Photothermal Threshold Quantum Yield

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 reach...
