Abstract
This study sought to investigate photoluminescence (PL) emission spectra of poly allyl diglycol carbonate (PADC) irradiated with short wavelength ultraviolet radiation of 254 nm. PADC samples were irradiated with UVC of 254 nm from UVC Corsslinker (Hoefer) with different doses ranging from 900 J/cm(2) to 180000 J/cm(2). The photoluminescence spectra of UV-irradiated PADC were measured with the aid of a spectrofluorometer (FluoroMax-4). The results revealed that the UVC of 254 nm induced modifications in the photoluminescence emission spectra of PADC. While the PL peak position shows insignificant changes, FWHM of PL increased from 9.92 eV of pristine PADC to 11.17 eV of PADC exposed to UVC dose of 900 J/cm(2), thereafter no significant changes were observed, irrespective the UVC dose. The photoluminescence peak intensity as well as the integrated photoluminescence intensity increases when there is an increase in the UVC doses and they are linearly correlated with UVC dose. These new findings indicate that it is possible to use photoluminescence emission spectra of PADC in dosimetric applications for ultraviolet radiation of short wavelength over a wide range of doses.
