Blue light-emitting diode (LED) has always been a tough problem for the display and illumination. Inorganic/organic semiconductors and carbon dots (CDs) with wide band gap still undergo the obstacles of...
Integration of blue light-emitting diode (LED) chips with yellow phosphors has been the most practical way to achieve white lighting, but finding a low-cost alternative for Y3Al5O12:Ce3+ (YAG:Ce) phosphors, which are expensive and lack red emission, is still a great challenge.
