Hydrothermal Synthesis Of CdSe Microspheres

Cadmium selenide (CdSe) microspheres have been synthesized by a cost-effective, simple and versatile hydrothermal deposition method onto soda-lime glass substrates. The thin films of CdSe microspheres were characterized for their optical absorbance/transmittance, optical band gap, photoluminescence and surface morphological study. CdSe microspheres show visible light absorbance of solar spectrum while is suffering from low optical transmittance. The optical band gap energy of CdSe microspheres was found to be 1.89 eV. Photoluminescence study involves one measure peak at 615 nm accompanying two more small peaks. The surface morphological study of CdSe thin film resembles a formation of microspheres which are interpenetrating with each other is seen at higher magnifications.
