“…These results are in good agreement with the reported observations [4]. Previous studies [21] showed that different doping of activation ion could influence photoluminescence (PL) characteristics of a phosphor. Usually, low doping gives weak luminescence but excess doping perhaps causes quenching of luminescence.…”

“…These include a decrease in luminescence due to oxidation, 16,17 reduced light output, and a color-shift in FL by ion bombardment or ultraviolet radiation. 18,19 Since current technology tends to develop compact FL, [20][21][22] the light output and color-shift problems have been aggravated by higher load on the phosphor. Therefore, previous studies on phosphor deterioration should be reviewed.…”

“…Previous studies (Kunzler et al 1992b: Tews et al 1992 showed that UV stability of rare earth doped phosphors depend upon the activator concentration and UV-induced damage of the phosphor decreases with increasing activator concentration. Hence it is worth to know the optimum activator concentration, Eu 2+ required to dope in BaMgAl~oO~v without luminescence quenching.…”
