Preparation of Eu3+-Y3+ coactivating Na+ based red-emitting luminous materials for light-emitting diodes and investigation of its characteristics.

By solid-state reaction and doping, a series of red-emitting phosphors Na(x)Y(0.92-x/3)(MoO(4))(y)(WO(4))(1-y)O(0.5) : zEu(3+) have been synthesized.

Instense red phosphors for UV light emitting diode devices.

Ca(x)Sr1-x-1.5y-0.5zMoO4:yEu3+ zNa+ red phosphors were prepared by solid-state reaction using Na+ as charge supply for LEDs (light emitting diodes).

A red-emitting phosphor and its luminescent properties.

Under 616 nm monitoring, excitation peaks at 395, 465, and 535 nm were observed for the red-emitting phosphor Li(0.3)Y(0.82)Mo(0.
