Photonic crystals (PC) can greatly enhance the optoelectronic performance of LEDs, due to their distinctive color and photonic band gap, etc. Therefore, many scholars have conducted extensive research based on the high light extraction efficiency, good monochromaticity, and other excellent optoelectronic properties of PC LEDs. This review discusses the main principles of photonic crystals to improve the optoelectronic performance of LEDs and summarizes 12 structural applications of photonic crystal LEDs, such as PC slabs, Bragg grating, Backside reflectors, Surface PC, Embedded PC, Dual PC, PC beads, CPC, PC thin films, LIPC, defective PC, composite architectures with other materials that boost LED optoelectronic qualities. In summary, it is found that photonic crystals can not only greatly improve the light extraction efficiency of LEDs but also improve other optoelectronic properties such as luminescent color, and directional radiation angle, and reduce the manufacturing cost of LEDs. Photonic crystal LEDs are expected to be a strong candidate for future lighting technology Finally, the prospects and challenges of PC LEDs are summarized.This article is protected by copyright.

In this paper, we propose a double-layer SiO2 photonic crystal LED with a linear defect structure in the [Formula: see text]-GaN layer, the purpose is to solve the problem of low light extraction efficiency caused by diffusion scattering effect. We used FDTD modeling to analyze the light-emitting characteristics of GaN LED, after optimizing the structural parameters of two-dimensional photonic crystals, the light extraction efficiency is improved from 19.4% to 35.2%, the light extraction efficiency is increased by 1.8 times, meanwhile the light output power is also increased by 1.86 times. The introduction of the defect structure does not affect the [Formula: see text]–[Formula: see text] characteristics of the LED, and the output power of the LED is increased by 11% under the current of 300[Formula: see text]mA.
