Boron nitride quantum dots for the efficient detection of Cu2+ based on photoluminescence spectroscopy
Boron nitride quantum dots (BNQDs) have emerged as promising materials due to their stability, oxidation resistance, and low toxicity. In this study, BNQDs were successfully synthesized via a simple hydrothermal method. FE-TEM, EDX, and XPS analyses confirmed spherical BNQDs with an average diameter below 5 nm. Photoluminescence analysis revealed concentration-dependent quenching with Cu2+ ions attributed to electron transfer mechanisms. The BNQDs demonstrated excellent water dispersion, outstanding photoluminescence, and high effectiveness as fluorescent probes for Cu2+ detection. With low-cost fabrication, straightforward synthesis, and remarkable selectivity, BNQDs hold significant potential for applications in environmental monitoring, water quality assessment, and advanced sensing technologies.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
