Abstract :
Crystalline tin selenide semiconductor was synthesized by a chemical route. Selenium powder reacted with potassium boronhydride, giving a soluble selenium species potassium seleniumhydride. The reaction of potassium seleniumhydride with tin chloride produced crystalline tin selenide, which was characterized by X-ray diffraction, 119Sn Mِssbauer spectroscopy and scanning electronic microscopy. The material was thermally treated, in nitrogen flow, at 300 and 600 °C for 2 h and the particle size evolution was studied by X-ray diffraction. The X-ray diffraction and 119Sn Mِssbauer results showed that a mixture of tin oxides and orthorhombic tin selenide was obtained.
