Eu-Activated Green-Emitting Phosphor Obtained from Eu Ions doping Zeolite-3A in Air Surroundings and Its Efficient Green Light-Emitting Diodes.

Eu-activated phosphors are widely applied in lighting and display areas because of their good optical performance. In this paper, an excellent green-emitting zeolite-3A: 1.3 wt% Eu phosphor is prepared by a green and eco-friendly high-thermal reaction method without any reducing atmosphere or agents.
