Tackling basic block-based anomaly execution behaviors

Enhanced Ce3+ photoluminescence by Li+ co-doping in CaO phosphor and its use in blue-pumped white LEDs

“…Although CaO is unstable since it reacts with atmospheric moisture or CO 2 to form Ca(OH) 2 or CaCO 3 , it can be improved by particle coating technologies such as those successfully performed on sulfides [4][5][6][7]. Recently, we found that replacing Na þ with Li þ to co-dope with Ce 3 þ can efficiently improve the photoluminescence intensity of CaO: Ce 3 þ .…”
