| 摘 要： | 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。 |
| 关 键 词： | 激光制冷 反斯托克斯荧光 罗丹明B PMMA 掺杂 制冷介质 |

| Abstract: | Through the comparative study on the solid solutions of the Rhodmine B in PMMA, theyare found to be effective to produce fluorescence. Spectrum analysis by fluorescence spectrophotometerreveals that the materials appear to produce anti-stokes fluorescence peak with excitation sources atwavelengths 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 0.11eV. |
