Abstract

The invention discloses an ultraviolet light-emitting chip, its preparation method and application. The ultraviolet light-emitting chip comprises, from bottom to top, a substrate, a buffer layer, an electron transport layer, an ultraviolet light active region, an electron blocking layer, and a hole transport layer. and a p-type layer; wherein, the ultraviolet light active region can simultaneously emit deep ultraviolet light and near ultraviolet light under forward current injection. The solution provided by the invention can solve the technical problem in the prior art that there is no single-chip ultraviolet light-emitting device that is relatively safe for users when used.

Description

technical field [0001] The present invention relates to the field of semiconductor technology, in particular to an ultraviolet light-emitting chip with alignment and warning functions. In addition, the present invention also relates to the preparation method and application of the ultraviolet light-emitting chip. Background technique [0002] At present, the ultraviolet light irradiation devices used in the market to sterilize articles and the environment are basically deep ultraviolet light-emitting devices. In fact, deep ultraviolet light is harmful to the human body to a certain extent. However, because human eyes cannot recognize the existence of deep ultraviolet light, in the process of use, users often inevitably find it difficult to notice deep ultraviolet light. Eyes and skin are stabbed by the deep ultraviolet light emitted by the deep ultraviolet irradiation device. In order to solve this problem, the existing solution is to remind the user by connecting related ...
