ABSTRACT:
An IR-to-visible converter for a solid-state image converting device including a photoconductive layer and an electroluminescent layer is sensitive to 1.5 .mu.m region IR rays and can convert such IR rays with high efficiency into visible light perceivable even in a well-lighted room. The IR-to-visible converter is characterized by using an IR to visible upconversion phosphors layer which has emission peaks in the sensitive wavelength region of the photoconductor layer, the IR to visible upconversion phosphors layer being optically combined with photoconductive layer.
