| 1 | Y_(4)GeO_(8):Er^(3+),Yb^(3+) up-conversion phosphors for optical temperature sensor based on FIR technique显示文摘Herein,we reported novel Y_(4)GeO_(8):Er^(3+),Yb^(3+)phosphors elaborated via conventional solid-state reaction.and we further explored their properties as optical thermometer by using fluorescence intensity ratio(FIR)method complemented by detailed analysis on crystal structure,up-conversion luminescence and energy transfer from Yb^(3+)to Er^(3+).Upon 980 nm laser excitation,Y_(4)GeO_(8):Er^(3+),Yb^(3+)phosphors present525,547 and 659 nm emission bands assigned to the characteristic transitions of Er^(3+).Furthermore,Y_(4)GeO_(8):Er^(3+),Yb^(3+)samples show outstanding temperature sensing performances.To be specific,the minimal temperature resolution is 0.03 K(303 K),and the relative sensitivity of FIR can be up to 1.152%/K(303 K).Hence,Y_(4)GeO_(8):Er^(3+),Yb^(3+)phosphors can be possible candidates for thermometry devices. | Yihang Chen Jing Chen Ye Tong Wenna Zhang Xiusha Peng Hai Guo Daxing Huang | 2021 | Journal of Rare Earths2021，39，12： | 5 |
| 2 | Tunable luminescence and energy transfer in Y_(2)BaAl_(4)SiO_(12):Tb^(3+),Eu^(3+)phosphors for solid-state lighting显示文摘Single-phase Y_(2)BaAl_(4)SiO_(12):Tb^(3+),Eu^(3+)phosphors with adjustable luminescence were successfully prepared by high-temperature solid-state reaction method.The structural,luminescent properties and ene rgy transfer(ET) process of Y_(2)BaAl_(4)SiO_(12):Tb^(^(3+)),Eu^(3+)phosphors were syste matically analyzed with the help of X-ray diffraction(XRD),scanning electron microscopy(SEM),excitation spectra,emission spectra and photoluminescence decay curves.Tunable luminescence ranging from green through yellow and definitively to red can be achieved by elevating amounts of Eu^(3+)ions in Tb^(3+),Eu^(3+)co-doped samples.Besides,the ET mechanism and efficiency were also analyzed and the maximum ET efficiency is 67%.All the results show that Y_(2)BaAl_(4)SiO_(12):Tb^(3+),Eu^(3+)phosphors can be used in solid-state lighting. | Jie Wang Xiusha Peng Danzhao Cheng Zhigang Zheng Hai Guo | 2021 | Journal of Rare Earths2021，39，3： | 3 |
