Abstract

Photoluminescent carbon dots of 4-5 nm size were prepared from starch (Tapioca Sago) through a solution method under mild conditions. The as-prepared carbon dots were used as photoluminescence probes for highly anion selective fluoride ion detection in aqueous solutions. A ready-to-use device is also demonstrated.

摘要

通过温和条件下的溶液法，由淀粉（木薯西米）制备出尺寸为4 - 5纳米的光致发光碳点。所制备的碳点用作光致发光探针，用于水溶液中高阴离子选择性氟离子检测。还展示了一种即用型装置。
