研究了罗丹明6G、罗丹明B和罗丹明101三种激光染料在乙醇和甲醇溶液中的紫外-可见吸收和发射性能。用时间分辨方法研究了每种染料第一激发态的衰变。利用皮秒激光脉冲研究了罗丹明6G、罗丹明B和罗丹明101的最低激发单重态吸收特性。S(n)的摩尔吸收系数值
The UV-VIS absorptive and emissive properties of three laser dyes, viz. Rhodamine 6G, Rhodamine B and Rhodamine 101, have been studied in ethanolic and methanolic solutions. Time-resolved methods were used to study the decay of the first excited singlet state of each dye. The absorptive properties of the lowest excited singlet states of Rhodamine 6G, Rhodamine B and Rhodamine 101 were generated using picosecond laser pulses. Values for the molar absorption coefficient for the S(n)
