^{Product Overview}

CsPbBr¡ãChas A typical Abx-¡ãCtype perovskite crystal structure, where the A position is cesium ion (Cs + +), the B position is lead ion (Pb² + +) and the X position is bromine ion (Brâï¿?. This crystal structure has a high degree of symmetry and stability. At the nanometer scale, quantum dots show obvious quantum limiting effect. With the decrease of quantum dot size, the movement of electrons and holes is restricted, which leads to the change of band structure and the separation of energy levels. For example, when the quantum dot size decreases from 10 nanometers to 5 nanometers, its band gap increases and the luminous color shifts from green to blue. Quantum dots typically range in size from a few nanometers to tens of nanometers. Quantum dots of different sizes and morphologies can be obtained by controlling the preparation conditions. The common morphology is spherical, cubic shape and so on. For example, in the preparation process of hot injection method, the growth rate of quantum dots can be controlled by adjusting the reaction temperature and time, thus affecting their size and morphology.
