Porous CdSe : CdO particulate structure formed by screen printing and sintering of Cd and Se powders in air

A porous CdSe particulate structure was formed by screen printing of high-p urity Cd and Se powders with CdCl2 as the flux, followed by sintering at hi gh temperature in air. The structural, morphological, optoelectronic and ph otoelectrochemical properties of the screen-printed CdSe structure depend o n the Cd/Se ratio (composition) and sintering temperature. The final coatin g consisted of a CdSe:CdO composite structure after sintering in air. This coating exhibited high photosensitivity and large-grain structure, which ma y be exploited for its use as a photoconductor in solid state devices and a s a photoelectrode in photoelectrochemical energy conversion processes.
