TY - JOUR T1 - study of the Infeluence of substrate temperature on structural and optical properties of sprayed ZnO thin films. TT - مطاله ی تاثیر دمای زیر لایه در خواص ساختاری و اپتیکی لایه های نازک اکسید روی تهیه شده با روش اسپری پایرولیزز JF - opsi JO - opsi VL - 21 IS - 0 UR - http://opsi.ir/article-1-822-en.html Y1 - 2015 SP - 1544 EP - 1546 KW - optical parameters KW - ZnO KW - spray pyrolysis N2 - In this study Influence of substrate temperature on structural, optical and electrical properties was investigated. The films have been deposited onto glass substrates by chemical spray pyrolysis at different substrate temperatures in the range, 350 - 500 centigrade.X-ray diffraction studies have shown that the films were polycrystalline and showed the hexagonal wurtzite structural of ZnO with (002) crystal plane as the preferred orientation.The film exhibited a maximum optical transmittance of > 70% and grain size value have been calculated and the maximum value is related to 400 °C temperature.
