Abstract
A radioluminescent source is provided by a radioactive element entrapped in an amorphous semiconductor. A preferred light source comprises a beta-emitting radioactive element, such as tritium, occluded within a matrix of amorphous semiconductor material, such as amorphous silicon, with or without dopants. The matrix may serve as an intrinsic radioluminescent light source, or as an electron source to irradiate a separate phosphor.
