Embodiment 1
[0029] (1) 0.4g of molybdenum disulfide, 2g of boric acid, and 2g of melamine were added to the beaker together, and the ultrasonic power was 140W with an ultrasonic machine for 1 hour, and the sol-gel reaction was carried out at 70°C for 5 hours, and the obtained solid was ground. , that is, the powder mixed with the three is obtained.
[0030] (2) The powder obtained in step (1) is placed in a porcelain boat, and under nitrogen protection, the temperature is raised to 400° C. at 5° C. / min, maintained for 2 hours, and then lowered to room temperature. The crude product was washed twice with water and twice with ethanol. After drying, boron and nitrogen double-doped molybdenum disulfide fluorescent nanomaterials can be obtained.
[0031] figure 1 The XPS results show that the nanomaterials obtained in Example 1 were successfully doped, figure 2 The test results of ultraviolet and fluorescence intensity of 1 show that the doped molybdenum disulfide obtained in Example 1 has...
