Optical Nonlinearities of the Polar Enhancement Metal-Oxide Semiconductor Particles

【摘要】 <正> 1 Introduction The materials with large and fast third-order nonlinearities are of considerable interest because of their important applications in all optical signal processing, optical computing and phase conjugation. Recently, the third-order nonlinear optical properties of semiconductor microparticles (such as CdS_xSe_1-x doped glasses) have received much attention. It is known that the PbS and CdS colloidal microparticles also have strong更多还原
