Description

technical field [0001] The invention belongs to the technical field of nano-luminescent materials, in particular to a method for rapidly preparing and screening IIB group semiconductor nano-luminescent materials. Background technique [0002] Today, with the rapid development of modern high-tech and high-tech industries, there is an increasing demand for new materials with specific functions. Therefore, accelerating the development of new materials is a major challenge facing the scientific community today. The chemical industry is undergoing a comprehensive structural adjustment in the global economy and sustainable development. Although the composition and structure of compounds are rich and diverse, it is still difficult to find new substances with specific functions. The traditional "stir-frying style" synthesis strategy is inefficient, which makes the discovery and optimization of new materials have disadvantages such as high cost, long cycle, low output and large chanc...
