玻璃基板上溶胶凝胶法铌酸锂薄膜的制备及其表征     

张一兵  翁文剑 《科技通报》2005,21(6):732-734

用溶胶凝胶法在玻璃基板上以LiNb（OR）6先驱体溶液（用甲酸作稳定剂,乙二酸作对照实验）制备了铌酸锂薄膜,并对薄膜进行了IR、XRD和SEM表征,结果表明,生成的铌酸锂为多晶,与乙二酸相比,用甲酸作稳定剂制备的铌酸锂薄膜形貌更好。  相似文献

We present a Monte Carlo （MC） method to simulate the scattering for medium within randomly distributed particles, discuss the convergence of this method by varying the size parameter ka. volume parameter η and calculation parameter Ni, then compare this method with the classical iteration method with the same parameters. The calculation results showed that this method has good convergence and accords with the iteration method while consuming less CPU time. At the end of this paper, this method is used to discuss the visual light scatter in the c-Si/α-Si films.  相似文献
