高压下激光染料分子的超快能量弛豫过程
Ultrafast energy relaxation process of laser dye molecules at high pressure
摘要
Abstract
The ultrafast molecular energy relaxation dynamic processes of LDS698 molecules at high pressure were studied by using the technique combined femtosecond time-resolved spectral measurement with high pressure generation.The results indicated that the LDS698 solution solidified at about 3.0 GPa.The pressure effects on the energy relaxation of the excited molecules are different.When the pressure is lower than 3.0 GPa,the pressure effects on the intra-and inter-molecular energy relaxation are all significant;and when the pressure is higher than 3.0 GPa,the pressure effect on the intra-molecular energy relaxation can be neglected,but the effect on the intermolecular relaxation is also significant.Using the theories suggested the pressure effects on the ultrafast energy relaxation are satisfactorily interpreted.The results also indicated that pressure could influence on the molecular energy gaps,the intermolecular interaction,and the solution thermal conduction.关键词
