| Abstract Scope |
Both zinc sulfide and zinc selenide have been used for optical windows and coatings due to a very low absorption coefficient across a wide wavelength range allowing both a desirable degree of transparency and high laser damage threshold. A low temperature process to prepare nanoengineered pure and ZnSe was performed using zinc acetate, sodium selenite and a capping agent to avoid agglomeration. We observed that the addition of the capping agent before or after chemical synthesis of ZnSe played very important role to control the size of nanoparticles and to avoid agglomeration. Size of nanoparticles of synthesized ZnSe was as small as 10 nm for both doped and undoped material. Cr-ZnSe nano particles showed fluorescence at different wavelengths, and higher bandgap than bulk Cr- ZnSe crystal grown by PVT method. The magnitude fluorescence intensity for Cr-ZnSe nanoparticles was higher compared to undoped ZnSe nanoparticles. |
