Transition-metal dichalcogenides like tungsten disulfide (WS2) are luminescent but still bear low quantum yields and hardly meet the requirement of practical applications. Here, we developed a hot-injection method to prepare highly luminescent WS2 quantum dots with tunable particle size in a noncoor...
