Structural, morphological and optical properties of ZnSe quantum dot thin films

Zinc selenide (ZnSe) quantum dot thin films have been deposited onto microscope glass through chemical bath deposition both from original amonia free alkaline precursors and modified precursors with the adding of sodium citrate as complexing agents. The growth and optical properties of samples from original and modified precursors have been investigated. Its shown that the samples obtained with sodium citrate precursors are uniform and with stable index of refraction. And with the adding of sodium citrate, there is an increase in transmittance.

Znse Thin Films

ZnSe thin films were obtained through chemical bath deposition method. Structural and optical properties of as deposited and annealed samples were investigated by X-ray Diffraction and spectrophotometer. The as deposited thin films were in nanocrystalline, with lots of strain and a blue shift of optical band gap. After annealing, the crystal grain gained, the strain eased and optical band gap enlarged. And it suggested that annealing can ease the quantum effect of chemical bath deposited ZnSe thin films.
