摘要

摘要: 测定了粉末罗丹明101（Rhodamine 101）及其在溶剂（甲醇、乙醇、水的混合液）中的高压荧光光谱。结果表明，粉末样品和溶液样品在高压下的发光性质有很大的区别。对于粉末样品，随着压力的增加，Rhodamine 101的荧光强度下降很快，在大约8 GPa时荧光峰几乎消失；伴随着荧光强度的变化，荧光峰峰位发生了显著红移（8 GPa内红移了近100 nm）。对于溶液样品，其荧光强度随压力的增加降低较慢，到13 GPa时，强度约为常压的10%，荧光峰峰位红移较小（13 GPa内红移约50 nm）。在压力作用下，Rhodamine 101分子结构的变化和特殊的溶剂效应，分别是影响其在粉末状态和溶液中荧光性质的主要因素。

Abstract: The fluorescence spectra of both Rhodamine 101 powder and solution (mixture of methanol, ethanol and water as solvent) have been measured under high pressures. It has been found that the emission character of Rhodamine 101 powder is quite different from that in solvent under high pressures. For Rhodamine 101 powder, the fluorescence intensity drops quickly with the increase of pressure and disappears almost at 8 GPa, while the emission peaks move redward dramatically (about 100 nm within 8 GPa). For Rhodamine 101 solution, the fluorescence intensity decreases slowly with the increase of pressure; the emission intensity at 13 GPa is about 10% of that at the ambient pressure. Moreover, the emission peak moves redward comparatively slowly (about 50 nm within 13 GPa). The change of molecular structure and special solvent effect are, respectively, the primary factors that influence the emission character of Rhodamine 101 powder and solution under high pressures.
