Comparative Study of Bulk and Nanoengineered Doped ZnSe

Chromium- and cobalt-doped zinc selenide nanoparticles were synthesized using a low-temperature reactive solution growth method. The morphological optical characteristics compared to those of doped (ZnSe) bulk crystals grown by the physical vapor transport (PVT) We observed agglomeration particles; however, thioglycerol capping agent has been shown limit particle grain agglomeration. This process enables doping addition chromium cobalt salts in solution. A slightly longer refluxing time was required achieve as with due lower temperature. nanoparticle showed an average size approximately 300 nm for both Cr- Co-doped selenide. characterization Co:ZnSe is ongoing; preliminary results very high bandgap that pure ZnSe crystal. Additionally, order magnitude higher fluorescence intensity Cr:ZnSe samples.
