摘要:

A number of 1,3-diphenyl-2-thiohydantoin azo dyes were purely prepared and characterized by spectroscopic analyses. Then the azo dyes were subjected to γ-radiation doses of up to 109rd. Results obtained indicated that the spectral bands of the investigated azo dyes suffer shifts, changes in intensity, broadening, creation of new bands and/or completely disappearance of others as a result of radiation damage. Furthermore a sequence for the relative stability of the different dyes towards gamma radiation damage was put forward.
