CdSe material is transparent to infra-red (IR) light and has seen limited use in photoresistors and in windows for instruments utilizing IR light. The material is also highly luminescent. CdSe is a component of the pigment cadmium orange. WebRefractive indexes of single hexagonal ZnS and CdS crystals, J. Opt. Soc. Am. 53, 496-497 (1963) 2) M. Sanchez Gomez, J. M. Guerra, and F.

WebAug 6, 2024 · In this work, we performed the extraction of pseudo refractive index of a NPL monolayer, whose thickness is around 5 nm and which consists of a single layer of negatively charged CdSe/CdS core–shell NPLs deposited on the top of the positively charged molecular layer on a SiO 2 (85 nm)/Si(bulk) substrate. WebApr 13, 2024 · The Swanepoel method was used to compute the refractive index, and it was found that the refractive index rises as the Cu doping levels rises. The optical band gap energy was observed to decrease from 2.225 eV to 1.941 eV as the Cu content rose from 0% to 8%, and then slightly increase to 1.965 eV at a Cu concentration of 10%. ...
