Example Embodiment

[0026] Example 1

[0027] A large number of organic-inorganic hybrid bismuth iodine anion cluster-based semiconductor materials (MV) 2 (Bi 4 I 16 ) Preparation of crystal samples: Weigh 0.603g (1mmol) of bismuth iodide and dissolve it in 40ml of acetone to obtain a clear solution A, and weigh 0.222g (0.5mmol) of methylviologen iodide and dissolve it in 8ml of water to obtain a clear solution. Solution B; Then, the above solution B was added to solution A, and it immediately formed turbidity. After the addition was completed, the reaction was stirred and reacted for half an hour to form a large amount of crystal products. The crystals were separated by filtration, washed twice with water and ethanol, and dried in vacuum. A large number of deep red crystals are the target products of the hybrid material, and the yield exceeds 80%.
