Abstract:
|
The wavelength dependence of thermal lens signal from organic dyes are studied using dual beam thermal lens
technique. It is found that the profile of thermal lens spectrum widely differ from the conventional absorption spectrum
in the case of rhodamine B unlike in the case of crystal violet. This is explained on the basis of varying contribution of
nonradiative relaxations from the excited vibronic levels. |
