“…In addition, unlike ZnO, ZnSe is also reported as a p- and n-type semiconductor, although it is still more difficult to realize an effective p-type than n-type ZnSe semiconductor . Till date, various ZnSe nanostructures have been investigated, − and many different methods have also been reported to prepare ZnSe films, such as chemical bath deposition, magnetron sputtering, coprecipitation method, molecular beam epitaxy, thermal evaporation, electrodeposition, pulsed laser deposition technique, and electron-beam evaporation . Among these preparation methods, electron-beam evaporation has the advantages of economy of materials, convenient operation, and environmental friendliness.…”

Cadmium-based quantum dots (Cd-QDs) show decent performance for lighting applications due to good color saturation, an excellent high quantum yield, and a narrow full-width at half-maximum. However, the intrinsic toxicity of Cd is a major hindrance to related applications, especially in the biological field. ZnSe, with a band gap of 2.7 eV and lower toxicity than CdSe or CdS, is promising as a blue luminescent material. Herein, we mainly reported the preparation and luminescence properties of nanostructured ZnSe/ZnS multilayer thin films with bright blue photoluminescence. The photoluminescence spectrum contained two emission peaks, located at about 442 nm (near band-edge emission) and 550 nm (defect-related emission), respectively. More importantly, the photoluminescence performance and decay were explored in detail through low-temperature photoluminescence spectra. In addition, the nanostructured ZnSe/ZnS multilayer thin films showed favorable photostability.
