摘要: 3种不同的荧光染料被分别嵌入硅基多孔氧化铝模板中,并且在室温下得到了蓝光、绿光和红光波长的荧光发射.实验中同时观测到上述荧光光谱的蓝移现象.研究结果表明,荧光染料沉积在不同的模板(如硅基多孔氧化铝、多孔硅)中,其相互作用的机理是不同的.模板发光机制的差异将直接影响荧光染料的发光性质.

Abstract: Si-based nanoporous alumina can be used as the host matrices for a variety of luminescent media to obtain light dots in nanometer size.In this experiment three kinds of fluorescent dyes are impregnated into Si-based nanoporous alumina and utilized to obtain blue, green and red emission at room temperature.The blue-shift of emission spectra is found and the interaction mechanism between the fluorescent dye and the host matrices such as nanoporous alumina and porous silicon is discussed.The results show that the PLproperties of fluorescent dye are directly affected by the PLmechanism of the host matrices.

Key words: Fluorescent dye, Photoluminescence, Porous alumina, Porous silicon
