Synthesis and luminescence properties of Y2O3:Eu with flower-like microstructure

The thermal stability and structural site-distribution of Eu3+ ions in the red-emitting phosphors Ca9Eu2W4O24 and Sr9Eu2W4O24

“…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.…”

Luminescent properties of Eu3+ ions in CaB6O10 polycrystals

“…In comparison to the other well-known and commercially used crystals, in the Y 2 O 3 the optimal Eu 3 þ concentration was between 5 and 9% depending on the synthesis condition [16]. The optimal concentration of Eu 3 þ ions was 7.5% as reported for the Y 3 Al 5 O 12 (YAG) and YAlO 3 (YAP) nanophosphors [17].…”

Facile route to produce spherical and highly luminescent Tb3+ doped Y2O3 nanophosphors

“…Figure 1(a-d) shows the XRD profiles of (a) S P , (b) S C , (c) S T and (d) S CT at 700 0 C. For comparison purpose we have also given the XRD profile of pure cubic phase Y 2 O 3 (JCPDS 83-0927) [15]. From these profiles one can see that samples prepared were in good agreement with the standard data of the pure cubic phase Y 2 O 3 with space group Ia3 [15]. No impurity peak was observed in these XRD patterns, indicating high purity of the synthesized • The sample containing CTAB as surfactant i.e.…”
