Abstract :
Tin dioxide (SnO2) microparticles have been grown on p-type Si (100) substrate by thermal evaporation method. The experiment was conducted at 1080oC, under 1.6% oxygen (O2) gas in atmospheric ambient. The prepared film were characterized using X-ray diffraction (XRD), field emission scanning electron microscopy (FESEM) equipped with energy dispersive X-ray spectroscopy (EDX) and photoluminescence (PL) measurement. The growth particles were crystalline with size ranging from 100 nm to 500 nm. The PL spectrum of the SnO2 microparticles exhibits a broad visible light emission with a peak centered at around 611 nm.
