| 摘 要： | 系统研究了罗丹明6G和罗丹明B的非线性吸收特性和荧光猝灭特性,结果表明它们在532nm的激光波长作用下,呈饱和吸收特性,在355nm的激光波长作用下呈现反饱和吸收特性,通过理论拟合得到了激发态吸收截面和能级寿命;并对荧光猝灭现象进行了解释,首次提出激发态吸收诱导荧光猝灭的理论.

| Abstract: | The nonlinear absorption and photoquenching for the solution of Rhodamine 6 G and Rhodamine B are measured in details. They show SA in 532urn and RSA in 355urn. The absorption cross-section and lifetime of the excited-states are evaluated by fitting theoretical calculations with the experimental results. The photoquenching character is introduced and a theory of photoquenching ,induced by excited-state absorption is presented. |
