Cation vacancy-boosted BaZnBO:Eu phosphors with high quantum yield and thermal stability for pc-WLEDs.

Achieving high luminescent quantum yield and thermal stability of phosphors simultaneously remains challenging, yet it is critical for facilitating high-power white light emitting diodes (WLEDs). Herein, we report the design and preparation of the layered structure BaZnBO:Eu (0.10 ≤ ≤ 0.

Synthesis, Photoluminescent Characteristics and Eu-Induced Phase Transitions in SrZrO:Eu Red Phosphors.

Designing phosphors that are excited by blue light is extraordinarily important for white light-emitting diodes (w-LEDs). In the present study, a new Ruddlesden-Popper type of SZO:Eu ( = 0.01~0.

Charge compensation engineering for high-performance dolomite-type BaTi(BO):Eu red-emitting phosphor for backlight display applications with a wide color gamut.

Exploiting high color purity phosphors is a core problem in the development of phosphor conversion light-emitting diodes (pc-LEDs) for display devices. Eu-activated BaTi(BO) (BTB) red-emitting phosphors were first synthesized a solid-state reaction at low temperature and alkali metal ions Na were co-doped in BTB:Eu to improve the luminescence properties. The occupation of the Eu ions and the enhancement principles of the Na ions and their effect on the photoluminescence properties of the BTB:Eu phosphors are discussed in detail.
