金殼生長求助
|
|
小弟目前在重復(fù)一篇文獻(xiàn),可是到了金殼生長階段總是出現(xiàn)問題,希望大家看到后能幫幫忙。 過程是In the gold shell growth step, 10 mg of potassium carbonate(K2CO3) were dissolved in 40 mL of water. After 10min of stirring, 1.5 mL of 0.01 MHAuCl4 solution was added. The solution initially appeared transparent yellow and slowlybecame colorless over 30 min. To this vigorously stirred solution, 500 μL of the Au-SSCNs solution (1.5 mg solid content) was added. Then, 500 μL (78.8 mM) aliquot of L-ascorbicacid was injected. After reacted for 5min, the solution changed to blue green, which indicatedthe formation of Au nanoshells. To investigate the growth process, different amounts of Au-SSCNs were added in the above growth solution for gold nanoshells formation。 加入抗壞血酸之后,溶液很快變成紫黑色,不一會兒有黑色顆粒產(chǎn)生。 產(chǎn)生這種現(xiàn)象的原因是什么呢,有知道的嗎? |
找到一些相關(guān)的精華帖子,希望有用哦~
