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。
The carbon quantum dots were prepared by hydrothermal method using citric acid as raw material, and the effect of the change of the nanoparticles on the luminescence intensity of luster refined chemical was studied. The experimental results show that the addition of carbon quantum dots to the conventional luminescent chemiluminescence system can significantly inhibit the chemiluminescence intensity of luminal, suppress the correlation between the signal and the concentration of carbon quantum dots, and optimize the photoluminescence, hydrogen peroxide and hydrogen Effect of Sodium Oxide Concentration on Luminescence Signal. Under the best experimental conditions, the decrease of luminescence signal and the concentration of carbon quantum dots showed a linear relationship with the concentration of 0.3 ~ 1.5 mmol / L carbon quantum dots, the correlation coefficient reached 0.9903.
