Abstract: Electro-luminescent output in the visible spectrum results from use of a GaAs infrared-emitting diode provided with a coating of a compound having at least one each of two different anions or at least one anion vacancy in some unit cells. The compound, exemplified by the oxychlorides and fluorochlorides, contains the ion pair Yb3 -Er3 , Yb3 -Ho3 , Yb3 -Tm3 or mixtures thereof.

Abstract translation: 可见光谱中的电致发光输出是由使用具有在一些单元电池中具有两种不同阴离子或至少一种阴离子空位中至少一种的化合物的涂层的GaAs红外发射二极管得出的。 该化合物，例如氯氧化物和氟氯化物，含有离子对Yb3 +，Er3 +，Yb3 + - Ho3 +，Yb3 + - Tm3 +或其混合物。
