Abstract

Electroluminescence excited by infrared radiation has been observed in GaP light‐emitting diodes (LED’s) at low temperatures providing a new efficient method to convert infrared radiation within a broad spectral range into visible light. Using 10.6‐μm radiation of a CO2 laser an up‐conversion quantum efficiency of 3.4×10−6 was found. If a low dark current photomultiplier is employed to detect the ...
