ULTRAVIOLET ORGANIC LIGHT-EMITTING APPARATUS

摘要

The present invention provides an ultraviolet (UV) organic light-emitting apparatus. The UV organic light-emitting apparatus comprises a UV organic light-emitting device and a passivation layer. The UV organic light-emitting device comprises a first electrode, a UV organic material layer and a second electrode formed in sequence. The passivation layer is disposed at a light emitting side of the UV organic light-emitting device, wherein the passivation layer is made of a transparent material showing a weak absorption in a UV spectral region. The present invention can mitigate the problems existing in the conventional UV lamp.

主权项

1. An ultraviolet (UV) organic light-emitting apparatus, comprising:
a UV organic light-emitting device comprising: a UV organic material layer for emitting a UV light, wherein a band gap of a material of the UV organic material layer is greater than 3.1 eV; a first electrode formed at one side of the UV organic material layer; and a second electrode formed at another opposite side of the UV organic material layer; and a passivation layer disposed at a light emitting side of the UV organic light-emitting device, wherein the passivation layer is made of a transparent material showing a weak absorption in a UV spectral region, and an absorptivity of the transparent material to the UV light is less than an absorptivity of a glass substrate to the UV light.
