Abstract
The photoluminescence (PL) and UV-vis spectral analysis of DAM-ADC (diallyl maleate: DAM, polyallyl diglycol carbonate: ADC) nuclear detector are demonstrated for the first time. The DAM-ADC surfaces were exposed to thin Am-241 disk source that emits alpha particles with activity 333 kBq. It is found that the track density of the irradiated samples remarkably influences the PL characteristics of the DAM-ADC detector. The spectral peak heights and the integrated intensities under the peaks exhibit linear correlations with correlation coefficient R-2=0.9636 and 0.9806, respectively for different alpha particle fluences ranging from 8.16-40.82 x 10(7) particles/cm(2). Additionally, a correlation coefficient R-2=0.9734 was achieved for the UV-vis spectral analysis. The linear fitting functions, along with the corresponding fitting parameters were evaluated in each case. Both the PL and the UV-vis data of the irradiated DAM ADC samples showed considerable spectral differences, and hence they would be used to offer sensitive approaches for alpha particle detection.
