Abstract
Recently phosphor materials which efficiently convert infrared (9300Å) radiation from Si : GaAs diodes to red, green, or blue light have been developed. The light sources which result from such diode-phosphor combinations are somewhat less efficient for red and green and are more efficient for blue than the best reported values for other solid state light sources. The basic mechanism of the conversion process including the important factors controlling the efficiency is discussed followed by the details of the efficient phosphor systems. The preparation of materials and its influence on efficiency is also covered.
