摘要：

Combined steady-state and time-resolved measurements are used to study solvation dynamics and statics of electronically excited dye molecules in solid melts of organic quaternary ammonium salts. Our results reveal the existence of solvation processes of various fluorophores in solid melts at room temperature. It was found that the solvation process in solid electrolytes is qualitatively similar but slower than the solvation in molten organic electrolytes. The time-dependent spectral shifts observed in the solid melts at room temperature are explained in terms of ion transport which takes place in solid electrolytes even at room temperature.
