WHITE ORGANIC-INORGANIC HYBRID ELECTROLUMINESCENCE DEVICE COMPRISING SEMICONDUCTOR NANOCRYSTALS

摘要

A white light-emitting organic-inorganic hybrid electroluminescence device which has nanocrystals as illuminants. According to the device, a semiconductor nanocrystal layer composed of at least one kind of nanocrystals, a hole transport layer and/or an electron transport layer simultaneously emit light to produce white light, or a semiconductor nanocrystal layer composed of at least two kinds of nanocrystals emits light at different wavelengths to produce white light. The device can be used as a backlight unit for a liquid crystal display, or can be used to manufacture an illuminator.
