PMN-PT透明陶瓷中气孔和晶界对光散射的影响分析
Light Scattering by Residual Pores and Grain Boundaries in Transparent 0.65PMN-0.35PT Ceramics
摘要
Abstract
The effects of the residual pores and birefringence of grain boundaries on the transmission through 0. 65PMN-0. 35PT electro-optic ceramics were studied with Mie scattering theory and the Raleigh-Gans-Debye model. Results show that both in-line transmission and total forward transmission decrease prominently with the increase of the porosity, while the transmission first decrease and then increase along with the increase of the pore size. The minimum of in-line transmission is achieved when the pore size is close to the wavelength of the incident light. Because of the optical birefringence at the grain boundaries, the in-line transmission decreases monotonically with the increase of grain size, and the total forward transmission is less sensible to the grain size.关键词
