title: Electrostatic Assembly Guided Synthesis of Highly Luminescent Carbon-Nanodots@BaSO4Hybrid Phosphors with Improved Stability.
abstract: Carbon nanodots (CNDs)@BaSO4hybrid phosphors are fabricated in an easy and low-cost process by sequentially assembling Ba2+and SO42-ions onto the surface of carbon nanodots through electrostatic attraction. CNDs act as the nucleus to attract these reactive ions and provide the luminescent centers in the hybrid phosphors. This strategy is versatile for a variety of negatively charged CNDs with different emission colors. The advantage of the resultant hybrid phosphors is that their luminescence exhibits excellent thermal and photostability, as well as remarkable resistance to strong acid/alkali and common organic solvents. These merits allow for the fabrication of CNDs-based light-emitting diodes using the CNDs@BaSO4hybrid phosphors as a color conversion layer.
