A new red phosphor BaGeF<sub>6</sub>:Mn<sup>4+</sup>prepared by a hydrothermal route shows intense emission under blue light excitation, which may find application in warm white LED devices.
Red phosphor Cs<sub>2</sub>GeF<sub>6</sub>:Mn<sup>4+</sup> synthesized by the cation exchange method exhibits an intense red emission with a high colour-purity. The warm WLED fabricated this emits white light under 20 mA current excitation.
Red-emitting phosphor Na<sub>3</sub>Li<sub>3</sub>Sc<sub>2</sub>F<sub>12</sub>:Mn<sup>4+</sup>with the high<sup>2</sup>E<sub>g</sub>level energy shows intensive red emission accompanied with high external quantum efficiency and thermal-quenching resistance for warm white LEDs.
A series of red phosphors Y 2 O 3 :Eu 3+ were prepared by the molten salt method with different surfactants. Their structures, morphologies, and photoluminescent properties investigated at room temperature. The particles size can be controlled adjusting kinds phosphor NP‐10 [polyoxyethylene (10) nonyl phenyl ether] shows regular morphology higher crystallinity, its average particle is about 200 nm. Bright light observed naked eyes from under 254 nm excitation.
Abstract Cs 2 GeF 6 :Mn 4+ is prepared by cation exchange through addition of K MnF and CsF to a GeO solution in HF (40 wt.%).
