Abstract
  Dy doped strontium aluminate phosphor (SrAl4O7:Dy(15% molar concentration)) was synthesized by combustion method using urea as a reducer at initiating temperature of 600oC. The absorption spectra shows the absorption edges at l = 242 nm, thus the band gap of 5.11 eV. The Thermoluminescence (TL) property ...  Read More
