以枝状聚乙烯亚胺和柠檬酸为原料，低温熔融法一步合成水溶性的氨基化碳点，碳点在紫外光激发下发出明亮的蓝光。采用傅里叶变换红外光谱和 X 射线粉末衍射仪对其结构进行表征，并研究其与碲化镉量子点在液相和固液界面的荧光共振能量转移。实验结果表明：液相中的荧光共振能量转移效率远大于固液界面的荧光共振能量转移，且能量转移具有一定的限度。

Amino-modified carbon dots were synthesized by the low temperature carbonization of citric acid in the pres-ence of branched polyethylenimine in one step.The bright blue emission was observed under the excitation of ultraviolet rays.Fourier transform infrared spectroscopy and X-ray powder diffraction were used to characterize its structure.Mean-while,the fluorescence resonance energy transfer between amino-modified carbon dots and CdTe QDs in liquid or solid-liquid phase was studied.The results show that fluorescence resonance energy transfer efficiency in liquid is much larger than the solid-liquid phase and it also has a limit.
