Abstract
The polycrystalline sample of KSr4 (BO3)3:Dy [KSBD] was successfully synthesized by novel solution combustion synthesis and has been studied for its thermoluminescence (TL) characteristics. The TL glow curve of the compound was composed of two peaks around 183°C and 314°C. The peaks are deconvoluted to determine kinetic parameters i.e. trap depth or activation energy and frequency factor from the glow curve by using peak shape method. Though the Zeff of KSBD material is very high, TL sensitivity of the phosphor was found to be as responsive as commercial phosphor TLD-100. Fading effect, variation of TL glow peak intensity with dose also been studied. The emission spectra monitored for 350nm excitation shows the characteristic emission of Dy3+ ions.
