Abstract

Fluorescent N,S-CDs with a quantum yield of 37.8% were synthesized a one-pot solvothermal method. Detailed characterizations on physical, chemical and optical properties have been investigated. N,S-CDs demonstrated remarkably quenched and enhanced fluorescence in acidic and basic media. Direct qualitative analysis in pH sensor and cell imaging were preliminarily studied.

摘要

通过一锅法溶剂热法合成了量子产率为37.8%的荧光氮、硫共掺杂碳点。对其物理、化学和光学性质进行了详细表征。氮、硫共掺杂碳点在酸性和碱性介质中表现出显著的荧光猝灭和增强现象。初步研究了其在pH传感器和细胞成像中的直接定性分析。
