PROCESSES OF EXCITATION RELAXATION IN MOLECULAR SYSTEMS FOR DIFFERENT TEMPERATURES
Journal Title: Сенсорна електроніка і мікросистемні технології - Year 2014, Vol 11, Issue 2
Abstract
In the work studying frequency and temperature dependence of quantum output of the methylene blue molecules and rezazurine molecules in the solid polymer solution are carried out. It has been found an empirical dependence for the constant of speed of excitation relaxation on difference between excited states and temperature: exp( ), 0 kT E k k b mn mn ∆ = ⋅ - ⋅ where b= 0,1. Modelling the processes of excitation relaxation allows to show that the experimental results can be described in supposing that not only electron-vibrational states, but interaction of these states with phonons of the solvent matrix participate in forming the UV absorption bands. As a result, it is obtained the theoretical dependence, which adequately describes the experimental results
