摘要：Modified LaB6 particles with sizes ranging from 50 nm to 400 nm were added into polymethyl methacrylate (PMMA) matrix in order to investigate the effect of added LaB_6 particles on optical properties of LaB _6/PMMA composites. Method of in-situ polymerization was applied to prepare PMMA from raw material - methyl methacrylate (MMA), a process during which LaB_6 particles were dispersed in MMA. Ultravioletvisiblenear infrared (UVvisNIR) absorption spectrum was used to study optical properties of the as-prepared materials. The difference in particle size could apparently affect the composites absorption of visible light around wavelength of 600 nm. Added LaB_6 particles with size of about 70 nm resulted in the best optical properties among these groups of composites.
