Dear Takaaki Nakada,

It will be useful for you to familiarize yourself with my mini-review and articles on this topic, and it's best to read the book in Russian if it is available to you.

The dependence of the fluorescence intensity on the polarity of the medium is well described, as a rule, for solvents that do not form a hydrogen bond with the molecule of the solute (dye) with the help of a formula that follows from my theory (see the book, or mini-review) for the rate of nonradiative transition. If in the processing of data the alcohols fall out of the general dependence (see conference paper), then the theory will be fulfilled for a separate group of low- viscosity alcohols.

Write to me, please, I will send inaccessible PDF-files to you.

Best regards

Hi Takaaki,

Solvent has large effect on absorption and emission spectrum.

what you observe is because of cut-off range(region) for solvent.at that region no signal will be observed,therefore check the cut-off region for solvent you are using. Good Luck
