ABSTRACT:
A method of manufacturing a gallium phosphide (GaP) red-emitting device by forming at least one n-type GaP layer on an n-type GaP substrate by the liquid phase epitaxial growth process and further depositing a p-type GaP layer on said n-type GaP layer, thereby providing a p-n junction contributing to emission of light, characterized in that the method comprises reducing the surface donor concentration of the n-type GaP layer to below 1 .times. 10.sup.18 cm.sup.-.sup.3 ; and epitaxially growing at least the light emitting region of the p-type GaP layer by cooling a solution for epitaxial growth of said p-type GaP layer at a slower rate than 5.degree.C per minute.
