Abstract
The effect of doping impurities and the container material on the color and intensity of electroluminescence (EL) of gallium phosphide crystals grown from the melt in gallium is considered. It is found that the maximum efficiency of red EL is observed in crystals grown in quartz containers, and of green EL — in crystals produced in alundum containers having aluminum nitride coatings. The optimal doping-impurity concentrations are determined for producing diodes with red, yellow, and green radiation.
