Simulated data for "Optical Study of Quantum Dot and Perovskite Light-Emitting Diodes Based on Simulation"

The optical simulation is mainly implemented by the commercial software Setfos.

Next-generation displays raise many challenging demands, such as wider color gamut, higher stability, and higher energy efficiency. Colloidal quantum dots (QDs) and metal halide perovskite materials are emerging optoelectronic semiconductors for the next-generation display. Compared with organic light-emitting diodes (OLEDs), the light-emitting diodes based on quantum dots (QLEDs) and perovskites (PeLEDs) exhibit tunable emission colors, narrow emission spectrum, high quantum yields, and low-cost solution processability.

Based on wave optics and nano-optics, the research investigated microcavity effect, surface plasmon polaritons (SPPs), dipole radiation, and the Purcell effect in QLED and PeLED, and proposed systematical routes for optical analysis and efficiency optimization. 

The research involves the following parts:

1. Wave optics and the dipole model of planar light-emitting diodes.

2. Optical design based on the microcavity effect, SPPs, and the Purcell effect. 

3. Light extraction strategy based on optical tunneling.

4. Full-color quantum dot light-emitting based on microcavities.

5. High-efficiency microcavity perovskite light-emitting diodes.
