2021年6月1日 · Two kinds of carbon quantum dots, C-dots-160 and C-dots-200 with different fluorescence luminescence behaviors were synthesized by a one-step hydrothermal method at 160 and 200 °C, respectively, using ammonium citrate as the raw material.

2024年7月1日 · We synthesized nitrogen and sulfur co-doped red carbon dots with a high QY of 34%. The red emission is caused by the increases of N and O content from sulfur doping. An integrated system is established to realize the LFPs imaging and fast recognition. We prepare RLEDs and WLEDs for indoor lighting to assist in plant growth.

Quantum dots have tunable optical properties that have proved useful in a wide range of applications from multiplexed analysis such as DNA detection and cell sorting and tracking, to most recently demonstrating promise for in vivo imaging and diagnostics.

2024年10月25日 · Colloidal solutions of gallium arsenide quantum dots of the type used in lasers, TVs, solar cells, medical devices, and other electronics glow under UV light. These were grown using a groundbreaking technique developed by UChicago’s Talapin Lab, a technique that opens a new world of materials for researchers growing nanocrystals.

Abstract: Fluorescent carbon dots (CDs) have attracted increasing attention in recent years owing to their most significant advantages in terms of low toxicity, resistance to photobleaching, small size, easy functionalization, eco-friendly synthesis and diverse imaging capabilities.
