EFFICIENT INFRARED-TO-VISIBLE CONVERSION BY RARE-EARTH OXYCHLORIDES

EFFICIENT INFRARED-TO-VISIBLE CONVERSION BY RARE-EARTH OXYCHLORIDES

When pumped by radiation from a Si–GaAs diode, the luminous efficiency of Y3OCl7:Yb3+, Er3+ is comparable to that of visible emitting GaP diodes. By varying the Yb3+ concentration, phosphors have been made which produce a red or yellow visual response.
