摘　　要：以柠檬酸为原料采用水热法制备了碳量子点,并研究了这种纳米粒子变化对光泽精化学发光强度的影响。实验结果表明,在传统的光泽精化学发光体系中加入碳量子点能明显抑制光泽精的化学发光强度,抑制信号与碳量子点的浓度具有相关性,并且优化了光泽精、过氧化氢和氢氧化钠浓度对发光信号的影响。在最佳实验条件下,在0.3~1.5 mmol/L碳量子点浓度范围内,发光信号的减弱值与碳量子点浓度呈线性变化关系,相关系数达到0.9903。In the present work,carbon quantum dots（ CQDs） were synthesized by hydrothermal method with citric acid as carbon sources. The effect of the synthesized CQDs on lucigenin chemiluminescence（ CL） was investigated. The results revealed that CQDs could inhibit lucigenin chemiluminescence,and the inhibiting effect of CQDs had relationship with its concentrations. The concentrations of lucigenin,hydrogen peroxide and sodium hydroxide could affect lucigenin CL. Under the optimal conditions,the CL signals varied linearly with CQDs concentrations in the range of 0. 3 mmol/L to 1. 5 mmol/L,with a correlation coefficient of 0. 9903.
