關(guān)于金納米簇的合成問(wèn)題
|
|||
| 我合成的金納米簇稀釋之前沒(méi)問(wèn)題,但是稀釋之后發(fā)射峰沒(méi)變,激發(fā)峰前面多出來(lái)一些尖峰,請(qǐng)問(wèn)這是什么原因造成的? |

What emission wavelength did you use for measuring the excitaiton spectrum? The peak at 323 nm looks like half of the emission maximum. In order to find whether the band in the range of 300-400 nm really contributes to the fluorescence emission, you can try to excite the Au NCs with 360 nm, which should lead to stronger fluorescence emission than that with 500 nm. |
