Nanosized Bi2O3 particles were prepared with the room-temperature solid-state method, the DMF/H2O system method, the glycol system method, and the size and shape of the particle was controlled by the additive of surfactant.

• 采用室温固相反应、选择DMF/H_2O体系及乙二醇体系等三种方法制备纳米Bi_2O_3，并通过在反应过程中添加分散剂来控制所得纳米粒子的粒径和形貌。
