Synthesis and luminescence characteristics of Na6Ca(1-)P2O9:X Dy3+ phosphor for outdoor lighting applications

A novel single-phase color tunable LiYGeO4:Dy3+, Eu3+ phosphor exhibiting warm white light and excellent thermal stability

“…1,2 Presently, white LEDs can be fabricated by combining blue LED chips with yellow phosphor YAG:Ce 3+ , or by blending red/ green/blue phosphors with ultraviolet (UV) chips. 3,4 However, the absence of red components makes the white beam have problems such as high color temperature correlation, low color rendering index and reabsorption, so in addition to finding an excellent red phosphor to make up for the lack of red light, the synthesis method of a single host phosphor can also solve this problem. [5][6][7][8][9][10][11][12] Therefore, more and more researchers are focusing on the development of a one-component white light-emitting material, which can solve the above problems in addition to simplifying the complex manufacturing process.…”
