Description

technical field [0001] The invention relates to a manufacturing method of a nano-optoelectronic device material, in particular to a manufacturing method of an up-conversion luminescent material. Background technique [0002] In the process of new energy research, solar energy, as a widely distributed, inexhaustible, inexhaustible and pollution-free green and clean energy, has become the first choice for the sustainable development of human society. Therefore, the research of solar cells that directly convert light energy into electrical energy has become a major subject of major investment and vigorous research and development by countries all over the world. The bandgap of single crystal silicon material at room temperature is 1.1eV, which just falls near the peak of solar radiation, and has a relatively high photoelectric energy conversion efficiency. Therefore, silicon-based solar cells have become one of the most promising materials at present and in the future. [000...

Problems solved by technology

For up-conversion materials, in the existing technology, the method of preparing rare earth-doped up-conversion luminescent materials is based on the use of oxides, carbonates, and hydroxide precursors of yttrium sulfide at high temperatures in a sulfur-containing atmosphere, or pyrolysis of sulfur-containing Single-source rare earth organometallic complexes, in these methods, must be carried out under high temperature conditions, which often leads to insufficient uniformity and dispersion of product particles, high synthesis costs, and cannot be combined with silicon-based solar cell technology
