Optimization of Synthesis Conditions of Mercury Selenide Thin Films
The mercury selenide (HgSe) films were obtained on glass substrates via the chemical deposition method. The aqueous solutions of mercury(II) nitrate, sodium thiosulfate, sodium selenosulfate and tri-sodium citrate were used. X-ray and elemental analysis of the film sample were made. The effect of initial reagents concentration, synthesis duration and temperature on the mass of HgSe films was investigated and coatings thickness was calculated. The optical and morphological properties of HgSe films were examined. The deposition mechanism is discussed.
