摘要：
We report a facile and low-cost synthesis of WS2 quantum dots with bright broad-band emission, which are suitable for lighting applications. The thus fabricated WS2 light-emitting diodes (LEDs) exhibit voltage independent electroluminescence spectra, and the optimized white LEDs generate a high color rendering index of 93.
