Carbon dot-based ratiometric fluorescent probe for the fluorescent "on-off-on" detection of Fe3+ and Amitrole herbicides In this study, a carbon dot-based ratiometric fluorescence (RF) probe was used as a fluorescent "on-off-on" sensor to detect Fe3+ and the pesticide amitrole (AMT). The RF probe consists of orange carbon dots (O-CDs) and blue carbon dots (B-CDs). B-CDs forms a ground-state complex with Fe3+ which leads to fluorescence quenching, while the addition of AMT restores fluorescence.

Achieving High Performance Ultra-Broadband Near-infrared Emission through Multi-site Occupancy and Energy Transfer Strategy for NIR LED Applications Broadband near-infrared (NIR) phosphor-converted light-emitting diodes (pc-LEDs) are considered to be at the forefront of the development of next-generation NIR light sources. However, the performance of NIR pc-LEDs is severely limited due to the narrow band emission, low quantum efficiency, and thermal quenching of NIR-emitting materials.
