Abstract
Conference Title: 2014 11th Annual High-capacity Optical Networks and Emerging/Enabling Technologies (HONET) Conference Start Date: 2014, Dec. 15 Conference End Date: 2014, Dec. 17 Conference Location: Charlotte, NC, USA Polyallyl diglycol carbonate (PADC) is a well-known Solid State Nuclear Track Detector (SSNTD). We have investigated structural modifications and optical properties of alpha irradiated PADC at different interval of times from 5min to 360min. Structural modifications are investigated from Scanning Electron microscopic (SEM) images and X-ray diffraction (XRD) patterns. Optical study is carried out from absorption and fluorescence spectra. XRD patterns confirm amorphous nature of the material but its diffracted intensities increase with increasing exposure time. SEM images show generation of nano size particles at the surface after 120 min exposure with alpha irradiation and the size increases with further exposure of the radiations. Absorption spectra show abrupt increase in absorption in UV range and slight variations are observed with further increase of exposure time. Increase in intensities of emission peaks are observed with alpha irradiation. Optical band gaps at different exposure are estimated using Tauc's plot
