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.

摘要:
Single crystals of NaClO3are prepared from aqueous solution of pure material. The effect of γ-irradiation on optical absorption, refractive index and indirect band gap energy as well as phonons assisting transitions are studied in the low absorption region. It is found no remarkable effect of γ-irradiation on the indirect band gap energy.
