“…There have been extensive studies on new phosphors for W-LEDs [3][4][5][6][7][8][9][10]. In particular Eu 3+ -doped oxyacid materials such as tungstates [11], silicates [14], vanadates [15], borates [16] and phosphates [11][12][13][14][15][16][17] have been investigated for red emitting phosphors.…”

“…Besides, Ce 3+ ion in vaterite-type LuBO 3 shows a broad and strong absorption band in the NUV region with peaked at 365 nm, which could act as a good sensitizer for Tb 3+ and Eu 3+ . Preliminary investigations on the photoluminescence of Ce 3+ , Tb 3+ , Eu 3+ , Pr 3+ single-doped [19][20][21], Ce 3+ /Yb 3+ co-doped LuBO 3 [22] were reported. However, detailed analysis on the PL properties of Ce 3+ /Tb 3+ co-doped and Ce 3+ /Tb 3+ /Eu 3+ tri-doped LuBO 3 have not been done yet to our knowledge.…”
