Effect of extra added Mg2+ and Si4+ on the microstructure and luminescence properties of Ce:YAG ceramic phosphors for high power LED/LD lighting

Concentration quenching inhibition and fluorescence enhancement in Eu3+-doped molybdate red phosphors with two-phase mixing

“…[1][2][3][4][5][6][7] Currently, a popular lighting solution for producing white light is the utilization of commercial blue uorescent LED chips combined with yellow light YAG:Ce 3+ phosphors. [8][9][10] However, the problems of high color temperature and low color rendering index need to be further solved in the warm white lighting eld due to the lack of red components. 11 With further research, Mn 4+ doped uoride red light material as an excellent candidate is gradually being utilized in the production of white LEDs to make up the shortcoming, but poor moisture resistance is the key factor restricting its promotion and application.…”
