This work demonstrates the possibility of synthesis of cadmium tungstate at low temperatures using oxide precursors. Cadmium tungstate (CdWO4) scintillator was produced via microwave-assisted hydrothermal reaction using the precursors CdO and WO3. The methodology was based on microwave radiation for heating, which is remarkably faster than the solid-state route or conventional hydrothermal procedure. CdWO4 monoclinic (wolframite) structure was successfully obtained at 120°C for synthesis times as short as 20 min. This route does not require the use of templates or surfactants and yields self-assembled nanorods with size of around 24 ± 9 nm width and 260 ± 47 nm length. The growth mechanism for the formation of CdWO4 involves microwave-induced dissociation of the reagents and solvation of Cd2

微波辅助水热法金属氧化物间短时间低温反应

这项工作证明了使用氧化物前体在低温下合成钨酸镉的可能性。钨酸镉 (CdWO4) 闪烁体是使用前体 CdO 和 WO3 通过微波辅助水热反应生产的。该方法基于用于加热的微波辐射，其速度明显快于固态途径或传统的水热过程。CdWO4 单斜（黑钨矿）结构在 120°C 下成功获得，合成时间短至 20 分钟。该路线不需要使用模板或表面活性剂，并产生尺寸约为 24 ± 9 nm 宽度和 260 ± 47 nm 长度的自组装纳米棒。CdWO4 形成的生长机制涉及试剂的微波诱导解离和 Cd2 的溶剂化
