LIGHT-EMITTING ELEMENT, LIGHT EMISSION APPARATUS, AUTHENTICATION APPARATUS, AND ELECTRONIC MACHINE

摘要

A light-emitting element includes an anode, a cathode, and a light emission layer. The light emission layer is arranged between the anode and the cathode and configured to emit light by energization between the anode and the cathode. The light emission layer includes a compound represented by a general formula NIR-D as a light emission material and a compound represented by a formula IRH-1 as a host material of the light emission material. The general formula NIR-D is;;in which each R independently indicates group comprising a phenyl group, a thiophenyl group, a furyl group, or at least one species of derivatives thereof. The formula IRH-1 is;;in which n indicates a natural number 1 to 12, and each R independently indicates a hydrogen atom, an alkyl group, an optionally substituted aryl group, or an arylamino group.
