摘要：

Eu3+ doped Y2O3 ceramic fiber phosphor with high aspect ratio was successfully fabricated by using direct ink writing(DIW) extrusion process combined with high temperature solid-state reaction method. The rheological properties of ceramic paste, phase structure and luminescence kinetic of ceramic fiber, as well as the temperature dependent photoluminescence(PL) spectra were successively investigated. The obtained results indicated that the optimal solid content was 55% for the ceramic paste with HPMC hydrogels as the additive. Pure ceramic phase could be achieved at the sintering temperature of >1 200 ℃. With increasing the temperature to 1 500 ℃, no significant change was observed for the phase structure. From the steady-state and transient PL spectra, the optimum luminescence performance was observed for the sample sintered at 1 300 ℃ with the luminescence lifetime of 1.12 ms. Finally, the temperature dependence of PL spectra was carefully studied, and the luminescence properties were not deteriorated with increasing temperature from 100 K to 500 K. Such a result may indicate an excellent luminescence thermal stability for our ceramic fiber. © 2021, Science Press. All right reserved.
