文摘	报道了罗丹明B掺杂PMMA材料制作过程及材料吸收和荧光光谱实验.吸收光谱表明,PMMA样品从紫外到近红外范围存在较小的吸收.罗丹明B/PMMA样品吸收光谱主要反映罗丹明B的吸收特征,其吸收峰中心波长位于550nm.荧光光谱显示,以630nm激发,反斯托克斯荧光峰位于595nm,能量差为0.11eV.该材料辐射反斯托克斯荧光,可用于激光制冷领域的研究.
其他语种文摘	Through the comparative study on the solid solutions of the Rhodmine B in PMMA, they are found to be effective to produce fluorescence. Spectrum analysis by fluorescence spectrophotometer reveals that the materials appear to produce anti - stokes fluorescence peak with excitation sources at wavelengths longer than those corresponding to the peak of the luminescent bend. This means fluores -cence photons have redundant energy than pumping photons. That is to say that the Rhodamine B -doped PMMAs are potential material for laser cooling. One of the materials we proposed is solid solu -tion of Rhodamine B in PMMA. It is excited at 630nm and produced fluorescence peak about 595nm, and has energy difference of 0. lleV.
