Journal ArticleDOI
New yellow Ba0.93Eu0.07Al2O4 phosphor for warm-white light-emitting diodes through single-emitting-center conversion
Xufan Li,John D. Budai,Feng Liu,Jane Y. Howe,Jiahua Zhang,Xiaojun Wang,Zhanjun Gu,Cheng-Jun Sun,Richard S. Meltzer,Zhengwei Pan +9 more
TL;DR: In this paper, a new yellow Ba0.93Eu0.07Al2O4 phosphor with a blue light-emitting diode (440-470 nm) was proposed for indoor illumination.
Journal ArticleDOI
Enhanced Red Emission in CaMoO4:Bi3+,Eu3+
TL;DR: In this article, the authors reported enhanced red emission at 613 nm originating from 5D0 → 7F2 transition of Eu3+-doped CaMoO4 with Bi3+ as an additive, under excitation either into the 5L6 state with 395 nm or the 5D2 state with 465 nm.
Journal ArticleDOI
Tunable full-color-emitting Ca3Sc2Si3O12:Ce3+, Mn2+ phosphor via charge compensation and energy transfer
TL;DR: White LEDs with high R(a) (> 90) are achieved using the single CSS:Ce(3+),Mn(2+) phosphor, which is a tunable full-color-emitting phosphor obtained by addition of doped ions as charge compensation.
Journal ArticleDOI
Tunable full-color emitting BaMg2Al6Si9O30:Eu2+, Tb3+, Mn2+ phosphors based on energy transfer.
TL;DR: Thermal quenching properties reveal that BaMg(2)Al(6)Si(9)O(30): Eu(2+), Tb(3+), Mn(2+) exhibits excellent characteristics even better than that of YAG:Ce, which can serve as a key material for phosphor-converted light-emitting diode and fluorescent lamps.
Journal ArticleDOI
An excellent cyan-emitting orthosilicate phosphor for NUV-pumped white LED application
Yongfu Liu,Jack Silver,Rong-Jun Xie,Jiahua Zhang,Huawei Xu,Hezhu Shao,Jun Jiang,Haochuan Jiang +7 more
TL;DR: In this paper, a cyan-emitting phosphor BLS:Ce3+ is reported that has a broad emission band covering both the blue and green regions of the visible spectrum.
