Abstract

851-854Eu doped strontium aluminate phosphor (SrAl2O4:Eu) was synthesized by combustion method using urea as a reducer at initiating temperature of 600°C. The mechanoluminescence (ML) of SrAl2O4:Eu and their suitability for radiation dosimetry have been investigated. Eu doped SrAl2O4 is a good dosimeter having linear response up to about 1180 Gy of -radiation dose. Two peaks have been found in time versus ML intensity curve. The peak of ML intensity versus time curve increases with increasing dose of <span style="font-family:Symbol; mso-ascii-font-family:" times="" new="" roman";mso-hansi-font-family:"times="" roman";="" mso-char-type:symbol;mso-symbol-font-family:symbol"="" lang="EN-GB">-radiation. The total ML intensity (area below the curve) also increases with -dose. </span
