以柠檬酸为帽型剂的水热法合成纳米CaWO4,综合透射电镜照片及其XRD表征结果得出合成产品的最优条件为:pH为7、柠檬酸用量为1:4,此时产品形貌为棒状。其中,柠檬酸的用量对产品最终形貌的影响尤为显著。纳米CaWO4样品掺入一定量稀土元素离子不会改变其结构,当Ce3+含量为2%,Eu3+含量为4%时,明显提高纳米CaWO4的荧光性能。
以檸檬痠為帽型劑的水熱法閤成納米CaWO4,綜閤透射電鏡照片及其XRD錶徵結果得齣閤成產品的最優條件為:pH為7、檸檬痠用量為1:4,此時產品形貌為棒狀。其中,檸檬痠的用量對產品最終形貌的影響尤為顯著。納米CaWO4樣品摻入一定量稀土元素離子不會改變其結構,噹Ce3+含量為2%,Eu3+含量為4%時,明顯提高納米CaWO4的熒光性能。

This topic focuses on nano--CaWO4 by hydro--thermal synthesis through taking the citric acid as capping agent. The TEM and XRD results indicate the most superior conditions to attain the product is: pH is 7, the amount of surfactant used is 1 : 4, the final appearance of product is rod, which is remarkably influenced by the amount of surfactant used. When the certain amuont of rare earth ion adding to the sample, it will not change the structure and the appearance of nano--CaWO4, when the amount of Ce3+ is 2% and Eu3+ is 4%, it will improve the fluorescence performance.
