New Yellow-Emitting Whitlockite-type Structure Sr1.75Ca1.25(PO4)2:Eu2+ Phosphor for Near-UV Pumped White Light-Emitting Devices
Haipeng Ji,Zhaohui Huang,Zhiguo Xia,Zhiguo Xia,Maxim S. Molokeev,Victor V. Atuchin,Victor V. Atuchin,Minghao Fang,Saifang Huang +8 more
TL;DR: A white LED device which is obtained by combining a 370 nm UV chip with commercial blue phosphor and the present yellow phosphor has been fabricated and exhibit good application properties.
Journal ArticleDOI
Structure evolution and photoluminescence of Lu3(Al,Mg)2(Al,Si)3O12:Ce3+ phosphors: new yellow-color converters for blue LED-driven solid state lighting

TL;DR: In this paper, the authors reported the development of new phosphors using the chemical unit cosubstituting solid solution design strategy, starting from Lu3Al5O12, the Al3+−Al3+ couple in respective octahedral and tetrahedral coordination was simultaneously substituted by a Mg2+−Si4+ pair forming the Lu3(Al2−xMgx)(Al3−xSix)O12:Ce3+ (x = 0.97Ce0.03Mg0.5Al4Si0
Journal ArticleDOI
Characterization of anion-cationic surfactants modified montmorillonite and its application for the removal of methyl orange
TL;DR: In this article, anion-cationic, anionic and cationic surfactants modified montmorillonite (MMT) are prepared by incorporating cetyl trimethyl ammonium bromide (CTMAB), anionic surfactant sodium stearate (SSTA) and their mixture to MT. The modified samples are characterized by X-ray diffraction (XRD), Fourier transform infrared (FT-IR) spectroscopy and Thermogravimetry-differential thermal analysis (TG-DTA).
Journal ArticleDOI
Discovery of New Solid Solution Phosphors via Cation Substitution-Dependent Phase Transition in M3(PO4)2:Eu2+ (M = Ca/Sr/Ba) Quasi-Binary Sets
Haipeng Ji,Zhaohui Huang,Zhiguo Xia,Maxim S. Molokeev,Victor V. Atuchin,Victor V. Atuchin,Minghao Fang,Yangai Liu +7 more
TL;DR: In this paper, the luminescence property of divalent europium (Eu2+) in the M3(PO4)2:Eu 2+ (M = Ca/Sr/Ba) quasi-binary sets was investigated.
Journal ArticleDOI
Comparative investigations of the crystal structure and photoluminescence property of eulytite-type Ba3Eu(PO4)3 and Sr3Eu(PO4)3.
