The Growing Popularity of Perovskite Quantum Dots
Over recent years we have seen an increase in popularity of perovskite quantum dots in the use of LCDs. This increase comes as it is more widely recognized that perovskite quantum dot-based LCDs have a greater color gamut and more vivid images.
Perovskite quantum dots have been shown to provide many optical advances for electroluminescent devices, including a wide wavelength tunability, narrow emission band, and high quantum yield. This enables the use of this new class of materials in high performance, lightweight, and low-cost LCD applications. In addition to LCDs, the use of perovskite quantum dots is also being explored in solar cells and photodetectors.
Crystal Structure and Chemical Formula of Perovskite Quantum Dots
When we refer to ‘Perovskite Quantum Dots’, perovskite is the crystal structure that the quantum dots possess. A perovskite is any material that has the crystal structure of XIIA2+VIB4+X2−3, and the general chemical formula of a perovskite is ABX3.
In this chemical formula, A is the monovalent cation, B is the divalent cation, and X is the monovalent halide anion that bonds to both.
Perovskite Quantum Dots Optical Properties
The outstanding optical properties of perovskite quantum dots is the reason for the increase in their popularity over recent years. Their beneficial optical properties include high emission purity, tunable emission wavelength, and large quantum yield.
For LCDs perovskite, quantum dots are beneficial due to the enhanced light and color they emit, which can be fine-tuned to exact specifications. This ensures that the colors produced are extremely precise.
Due to their small size and the reduction in the number of components required, perovskite quantum dots also help to reduce the size of displays, which is under high demand. They also provide a wider viewing angle.
