| 4 | To tune europium valence by controlling the composition in diphase silicate phosphors显示文摘Commercial phosphors always require fewer impurities and higher crystallinity, but sometimes it is difficult or strict to synthesize a pure phase compound. Indeed, if the practical application is not influenced, it is acceptable to synthesize a kind of phosphors with diphase matrix that have similar structure and photoluminescence properties. In present work, we designed and synthesized a series of(1-x)BaMSiO_4·xBa_2 MSi_2 O_7:Eu(M = Zn^(2+), Mg^(2+)) diphase phosphors which contained two phases BaMSiO_4(hexagonal, P63) and Ba2 MSi_2 O_7(monoclinic, C2/c) by a high temperature solid-state reaction in air condition. The structures and luminescence properties related to the phase transform from BaMSiO_4 to Ba_2 MSi_2 O_7 were analyzed carefully. The results show that the self-reduction ability of Eu^(3+) is not the best in above four compounds, respectively. But it reaches the maximum and gets the green emission under the UV lamp when the matrix is in a proper ratio of two phases, which suggests that the heterostructure between the two crystals(BaMSiO_4 and Ba_2 MSi_2 O_7) improves the self-reduction process of the diphase.The possible mechanism of the tunable europium valence and the luminescent properties in(1-x)BaMSiO_4·xBa2 MSi_2 O_7:Eu phosphors were discussed in detail. | Yiting Lin Jukui Zhou Zhongxian Qiu Wenli Zhou Jilin Zhang Chengzhi Li Liping Yu Shixun Lian | 2018 | Journal of Rare Earths2018，36，10： | 0 |
| 5 | Fine controllable blue emission and its mechanism in Ce^(3+)-doped orthosilicate solid solution phosphors for different plant growths显示文摘The designed Ce^(3+)-doped alkaline-earth silicate phosphors Ca_mSr_(2-m-n)Ba_nSiO_4:Ce^(3+),Li^+(CSBS:Ce^(3+))were synthesized by a high temperature solid-state reaction. The crystal field splitting and the centroid shift from the free ion energy of 5 d configuration were approximated from the spectrum for Ca_2SiO_4,Sr_2SiO_4 and Ba_2SiO_4 phosphors. The single-phase purity was checked by means of X-ray diffraction. Here,when the doped concentration of Ca^(2+) is less than 80%(m ≤1.6), we report the structural phase transformation from monoclinic system β-Ca_2SiO_4 to orthorhombic system α-Ca_2SiO_4. The phosphors excited by near-ultraviolet(NUV) light at wavelengths ranging from 200 to 400 nm demonstrate a broad asymmetric blue emission band. The emission peak wavelength redshifts firstly from 417 nm of Ca_2SiO_4 to 438 nm of Sr_(0.3)Ca_(1.6)SiO_4, and then blueshifts to 411 nm of Sr_2SiO_4, and the end of 401 nm of Ba_2SiO_4.These results indicate that the tunable blue-emission of the phosphors can be realized through changing the solid solution components, which has a potential use as a blue component for fabricated precision modulation LEDs light sources and auxiliaries of SSC plastics films for different plant growths.We discuss in detail the possible mechanism and energy diagram of the tunable blue luminescence in Ca_mSr_(2-m-n)Ba_nSiO_4:Ce^(3+),Li^+ phosphors. | Yaru Yang Yiting Lin Yue Han Zhongxian Qiu Wenli Zhou Jilin Zhang Chengzhi Li Liping Yu Shixun Lian | 2018 | Journal of Rare Earths2018，36，11： | 0 |
