Phosphors for white light-emitting diodes (WLEDs) would suffer from inadequate luminescent thermal stability, especially at high temperatures, affecting both the reliability and lifespan of devices. Thus, development phosphors with excellent stability is a crucial task. By use high-temperature solid-state reaction method, series Tb3+ Eu3+ codoped NaGd2Ga3Ge2O12 (abbreviated as NGGGO) has been successfully synthesized. With an appropriate doping concentration Eu3+, NGGGO:Tb3+,Eu3+ can provide color tunable emissions; simultaneously, energy transfer (ET) efficiency to reach nearly 100%. Notably, high-concentration in NGGGO could induce oxygen vacancies, giving significant enhancement on luminescence. For NGGGO:60% Tb3+,1.6% phosphor, emission intensity 450 K remained even higher than that observed under room-temperature conditions. as-synthesized phosphor red converter, near-ultraviolet pumped WLED device be fabricated. Under driving current 20 mA, exhibits rendering index (CRI) ∼ 89, low correlated temperature (CCT) 4603 K, bright light CIE chromaticity coordinates (0.3569, 0.3587), which demonstrates potential application.

Single-phase full-spectrum white-emitting phosphors with individual activator are of great significance for avoiding unnecessary energy loss and realizing high luminescence efficiency. Herein, a novel Na2Ca17Al2(PO4)14:Eu2+ phosphor is designed the strategy cation substitution functioned in regulating luminescence. The could realize basic emission under excitation 335nm, but lack red-light component CIE color coordinates (0.2291, 0.2302) can not meet requirements white light-emitting diodes (WLEDs). With partial or even full Na+ host Li+ ions, efficiently improved each emitting reaches appropriate proportion, achieving cold light at (0.3330, 0.3179). By further wavelength, Li2Ca17Al2(PO4)14:Eu2+ finally exhibits bright warm (0.3551, 0.3448) upon 360 nm internal quantum efficiency 33.2%. It due to by ions that contributes redistribution Eu2+ different crystal sites regulates photoluminescence this phosphor, emission. fabricated two WLED devices material near ultraviolet chips show outstanding rendering index 92.7 96.8, respectively, revealing has promising prospect field illumination.
