中文摘要 | the samples of as-synthesized siliceous mcm-41, extracted mcm-41, amorphous silica particles and silica xerogels were heat treated from room temperature to 1000degreesc. their photoluminescence (pl) spectra at room temperature excited by 254nm and 365nm ultraviolet light (uv) were investigated and compared. excited by 254nm uv the mcm-41 samples do not display pl but amorphous silica particles and silica xerogels show pl, which changes with the heat treatment conditions for the samples. however, when excited by 365nm uv the pl spectra for the mcm-41 and the amorphous samples are similar. the carbon impurity and e' center mechanisms can be ruled out as the origin of pl in siliceous mcm-41 under uv excitation. the pl of mcm-41 series samples probably originates from oxygen-related defect center like dropsi-o-. according to the present work. |
