查询词典 peacock copper

Under the optimized conditions, the relative fluorescence intensity decreased linearly with the copper ions concentration in the range from 2 to 200μg·L~(-1) and the detection limit could reach 0.29μg·L~(-1). Based on the charge-transfer quenching mechanism, the copper ions bounding onto the surface of qdots could absorb electrons from valance band, which results in the quenching of fluorescence.

用电荷转移机制解释了量子点荧光猝灭的原因，主要是由于价带电子激发到导带以后被表面结合的Cu~(2+)离子捕获而产生的结果，在此基础上，用光解实验进行了进一步的验证。

Main contributions and results of this research include: The production of nano-copper brei from adequate selection of some accessory ingredients based on the technology of super-fine powder preparation and the fundamental of surface chemistry. Best composition of materials for making nano-copper brei was subsequently determined by a series of orthogonal experimental approaches.
