Preparati.n and Structural Properti.s of Sprayed Lanthanum Oxi.e Fi.ms from an Aqueous Precursor

材料科学与工程（中英文A版） 2011年第1X期1卷 1-8页

作者： Mohamed K. Zayed mostaf.A. mostaf. Mohamed Ebai. Physi.s Department Faculty of Science Beni-Suief University Bani-Suief Egypt

Spray pyrolysi. techni.ue was used to prepare lanthanum oxi.e fi.ms (La2O3) from 0.01 M-aqueous soluti.ns of hydrated lanthanum chlori.e on hot (300, 350, 400 and 450 °C) fused si.i.a substrates. X-ray di.fracti.n (XRD) of fi.ms sprayed at temperatures between 300 and 400 °C showed the formati.n of cubi. La2O3 phase wi.h decreasi.g content of i.complete pyrolysi. phases; nonhydrated lanthanum chlori.e and lanthanum chlori.e hydroxi.e. Fi.ms deposi.ed at 450 °C showed amorphous structure. Thermo-gravi.etri. analysi. (TGA) and di.ferenti.l thermal analysi. (DTA) of a dri.d precursor also showed two stable thermal pyrolysi. temperature ranges; between 200 °C and 370 °C and above 470 °C, correspondi.g to i.complete pyrolysi. and stable oxi.e phase formati.n, respecti.ely. Thus, amorphous La2O3 fi.ms deposi.ed at 450 °C were annealed at temperatures between 550 and 850 °C for 1 h i. ai.. XRD of annealed fi.ms showed the formati.n of polycrystalli.e hexagonal La2O3 phase wi.h 100- and 001- mi.ed ori.ntati.ns at lower anneali.g temperatures. As the anneali.g temperature i.creased, the 001-fi.m texture i.creased on the expense of the 100-ori.ntati.n. Furthermore, i.creasi.g the anneali.g temperature reduces the di.ensi.ns and the volume of the formed hexagonal La2O3 uni. cell. The morphology of the annealed fi.ms was studi.d usi.g scanni.g electron mi.roscope.
