265nm UV LED, or ultraviolet light-emitting diode with a peak emission at 265 nanometers, has become a hot topic in the lighting industry due to its unique properties and potential applications. This article aims to provide an in-depth introduction to the 265nm UV LED industry, covering its basic principles, technology development, market trends, and future prospects.

Basic Principles of 265nm UV LED

265nm UV LED is a type of semiconductor device that emits ultraviolet light with a peak wavelength of 265 nanometers. The basic principle of UV LED is the photoelectric effect, which is the process of converting electrical energy into light energy. When a forward bias voltage is applied to the UV LED, electrons and holes are injected into the active region, where they recombine and emit ultraviolet light.

The active region of a 265nm UV LED is typically composed of a GaN (gallium nitride) layer sandwiched between two AlGaN (aluminum gallium nitride) layers. The GaN layer acts as the active layer, while the AlGaN layers serve as the n-type and p-type electrodes. The ultraviolet light is emitted from the surface of the GaN layer when electrons and holes recombine.

Technology Development of 265nm UV LED

The development of 265nm UV LED technology has gone through several stages. Initially, researchers focused on improving the quality of the GaN layer and optimizing the structure of the UV LED. In recent years, significant progress has been made in the following aspects:
