The electroluminescent properties of Er-doped GaP light emitting diodes are reported. Diodes were prepared by metalorganic vapor phase epitaxy and zinc diffusion. Strong characteristic Er3+ emission at 0.80 eV (1.54 μm) under forward bias is detected at room temperature. Minimal thermal quenching of the electroluminescence was observed. The luminescence intensity depended linearly on current density for low applied current densities, and saturated at a current density of 17 A/ cm2
