“…Moreover, its tunable optical band gap allows Cd 1-x Zn x S to be used for short wavelength optoelectronic devices such as blue, violet, or even ultraviolet LED's, laser diodes and photodetectors. [10][11][12] Apart from optoelectronic applications, CdZnS also has potential applications in photoelectrochemical devices such as photoelectrochemical (PEC) cells (for solar energy conversion) [13] and photoelectrochemical/ photocatalytic cells for splitting of water for hydrogen production. [14][15][16][17][18] Cd 1-x Zn x S is preferred over CdS for photoelectrochemical/photocatalytic splitting of water because A series of nanocrystalline thin films of cadmium zinc sulphide (Cd1-xZnxS) solid solution were deposited on glass substrates using spray pyrolysis.…”
