Perovskite Quantum Dots Supplier - Alfa Chemistry

Oxide Core-shell Hybrid Perovskite Quantum Dots


Organic-inorganic hybrid perovskite quantum dots (QDs) have wide applications such as solar cells, light-emitting diode, CO2 reduction and photocatalytic pollution degradation due to their advantages of high photoluminescence (PL) quantum yield, tunable band-gap, low defect density, long carrier life-time, broad emission spectra tunability and short radiative life-times. However, the ion diffusion rate is very low, so oxides (such as SiO2, Al2O3, ZrO2, TiO2, etc.) are often used as isolation layer materials to encapsulate the perovskite to enhance its stability. Alfa Chemistry has experienced researchers in quantum dot research, relying on advanced instruments and techniques, and can bring significant optimization services for Perovskite quantum dot lasers.

Oxide Core-shell Hybrid Perovskite Quantum Dots


The biggest challenge of organic-inorganic halide perovskite QDs is the instability due to their large specific surface area and high activities. They are easily decomposed in the environments of moist air, strong light illumination, acid, base and high temperature.

Oxide can be selected as the isolation layer material to encapsulate organic-inorganic hybrid perovskite quantum dots, thereby enhancing its performance. Among them, SiO2 has certain mechanical strength and airtightness, not only has high optical transparency, but also can effectively hinder or slow down the penetration of moisture and oxygen, and at the same time can also have a high resistance to temperature.
