Embodiment 1
[0022] Weigh bismuth nitrate pentahydrate and sodium bromide at a molar ratio of 1:1.1, grind the mixture of the two in an agate mortar for 5 minutes, then transfer the ground mixture to a planetary ball mill for high-speed grinding reaction, wherein the ball milling speed is 3000rpm, and the ball milling time is 3min; after the ball milling is finished, the intermediate product is taken out from the ball mill tank; it is dispersed in deionized water, and the amount of 2.5mg intermediate product added per milliliter of deionized water is added; after the addition is completed, put Put it into a hydrothermal reaction kettle and react at 100°C for 8 hours. After the reaction, cool down to room temperature naturally, centrifuge, wash with water and alcohol in sequence, and dry at 60°C.
Embodiment 2
[0024] Weigh bismuth nitrate pentahydrate and sodium bromide at a molar ratio of 1:1.3, grind the mixture of the two in an agate mortar for 5 minutes, then transfer the ground mixture to a planetary ball mill for high-speed grinding reaction, wherein the ball milling speed is 3000rpm, and the ball milling time is 3min; after the ball milling is finished, the intermediate product is taken out from the ball mill tank; it is dispersed in deionized water, and the amount of 2.5mg intermediate product added per milliliter of deionized water is added; after the addition is completed, put Put it into a hydrothermal reaction kettle and react at 110°C for 7 hours. After the reaction, cool down to room temperature naturally, centrifuge, wash with water and alcohol in sequence, and dry at 60°C.
Embodiment 3
[0026] Weigh bismuth nitrate pentahydrate and sodium bromide at a molar ratio of 1:1.5, grind the mixture of the two in an agate mortar for 5 minutes, then transfer the ground mixture to a planetary ball mill for high-speed grinding reaction, wherein the ball milling speed is 4000rpm, and the ball milling time is 2.5min; after the ball milling is finished, the intermediate product is taken out from the ball mill tank; it is dispersed in deionized water, and the amount of 2.5mg of the intermediate product is added per milliliter of deionized water; after the addition is completed, Put it into a hydrothermal reaction kettle and react at 120°C for 7 hours. After the reaction, cool down to room temperature naturally, centrifuge, wash with water and alcohol in sequence, and dry at 60°C.
