Scheelite type tungstate based red phosphors, CaLa1-xSbWO8:xEu(3+) (x = 0.05, 0.10, 0.15, 0.20 0.25, 0.50 and 1) were synthesized by the conventional solid state method. The crystalline structure, morphology and photoluminescence ...

Scheelite type red phosphors CaLa1-xNbWO8:xEu(3+) (x = 0.01, 0.03, 0.05, 0.1, 0.15, 0.2, and 0.25) and CaLa0.8-yNbWO8: 0.2Eu(3+), yBi(3+) (y = 0.1, 0.15, and 0.2) were prepared by conventional solid state reaction route. ...

A new orange-red emitting phosphor La3−xNbO7:xEu 3+ (x=0.05, 0.10, 0.15, 0.20) was prepared by a solidstate reaction route. Studies revealed the incorporation of Eu 3+ into two differently coordinated La 3+ sites, thereby ...

We report the photoluminescence properties of a novel powellite-based red-emitting phosphor material: CaLa1−xNbMoO8:xEu3+ (0.01, 0.03, 0.05, 0.1) for the first time. The photoluminescence investigations indicated that ...

New red phosphor materials of general formula Gd3-xMO7:xEu(3+) (M = Nb, Sb, and Ta) were prepared using a high temperature solid state reaction route. Detailed structural studies using XRD, FT-IR and Raman spectroscopic ...
