A method for gram-scale synthesis of graphitic carbon nitride quantum dots (g-CNQDs) was developed. The weight of the g-CNQDs was up to 1.32 g in each run with a yield of 66 wt%, and the purity was 99.96 wt%. The results showed that g-CNQDs exhibit a stable and strong ultraviolet photoluminescence at a wavelength of 365 nm. More interestingly, the g-CNQDs can be used as a high-efficiency, sensitive, and selective fluorescent probe to detect Fe with a detection limit of 0.259 μM.
开发了一种用于克级合成石墨相氮化碳量子点（g-CNQDs）的方法。每次运行中g-CNQDs的重量高达1.32 g，产率为66 wt%，纯度为99.96 wt%。结果表明，g-CNQDs在365 nm波长处表现出稳定且强烈的紫外光致发光。更有趣的是，g-CNQDs可用作高效、灵敏且选择性的荧光探针来检测铁，检测限为0.259 μM。
