ZnO納米粒子制備方法
|
||
|
有沒有制備ZnO納米粒子的蟲子? 我是按照文獻(xiàn)《Synthesis of ZnO Nanoparticles with Tunable Emission Colors and Their Cell Labeling Applications》中所采用的方法! 有沒有利用相同的方法? ZnO nanoparticles were prepared through a precipitation method by using LiOH as the precipitation agent in ethanol. In general, 0.2 mmol of zinc acetate was dissolved in 20 mL of absolute ethanol. The mixture was dissolved completely by being stirred at room temperature for 30 min; 36 mg of LiOH was dissolved in 20 mL of absolute ethanol. The zinc acetate/ethanol solution was then added to the LiOH/ethanol solution. The pH value of the solution was measured to be 12. After reaction for 2 h, the solution became turbid, indicating ZnO nanoparticles were formed. The pH values of the solutions were tuned to 10, 8, and 6 when 14, 10, and 5.5 mg of LiOH were added, respectively. 方法中沒有提及攪拌和溫度!所以我是在室溫?cái)嚢锠顟B(tài)下操作的,但是制備后溶液是完全透明狀,這樣是不是合理? |
