Description
MgO (Norton), on u.v. and γ irradiation, exhibits TL glow peaks around 88, 150, 172, 195 and 250degC (heating rate 55degC min-1). TL emission is observed around 340, 390, 445 and 705 nm and can be attributed to the impurities Fe3+ and Cr3+, which act as luminescence centers. ESR studies rule out any participation of Mn2+ ions. The glow peak around 88degC has E = 1.055 eV, s = 4.3 x 1013s-1 and has order of kinetics b = 1.7. (author)
