Abstract

PURPOSE: To enhance color rendering properties of a red light-emitting fluorescent material by substituting part of Y with a given amt. of trivalent Eu as an activator to obtain Y2O3.Ta2O5:Eu3+.
CONSTITUTION: Y2O3, Ta2O5 and Eu2O3 each in a given amt. are mixed and fired at 1,300W1,600°C for 2W20hr, and Y is partially substituted with 2W 16atom%, based on Y, trivalent Eu as an activator. The obtd. red light-emitting fluorescent material of Y2O3.Ta2O5:Eu3+ has a main luminance peak at a wavelength near 614mm under excitation pressure by UV rays, electron beams, etc. and is excellent in color rendering property.
