Sun Bingheng,Le Zhang,Le Zhang,Le Zhang,Tianyuan Zhou,Tianyuan Zhou,Shao Cen,Lei Zhang,Yuelong Ma,Yuelong Ma,Qing Yao,Qing Yao,Zhigang Jiang,Zhigang Jiang,Farida Selim,Hao Chen +15 more
TL;DR: In this article, vacuum as-sintered high quality Ce:YAG ceramics were subjected to various annealing conditions, and their microstructural evolution, and optical and luminescence properties were monitored and studied systematically.
Journal ArticleDOI
Room temperature continuous-wave laser performance of LD pumped Er:Lu_2O_3 and Er:Y_2O_3 ceramic at 27 μm
TL;DR: The study indicates that under 967 nm and 976 nm LD pumping, 15 at.% Er-doped Lu 2O3 ceramic exhibit a better performance than that of Y2O3 at room temperature.
Journal ArticleDOI
Toward vacuum sintering of YAG transparent ceramic using divalent dopant as sintering aids: Investigation of microstructural evolution and optical property
Tianyuan Zhou,Tianyuan Zhou,Le Zhang,Le Zhang,Zheng Li,Zheng Li,Wei Shuai,Jiadong Wu,Lixi Wang,Hao Yang,Zhenxiao Fu,Hao Chen,Dingyuan Tang,Ching-Ping Wong,Qitu Zhang +14 more
TL;DR: In this paper, the effects of divalent dopants on their microstructure evolution and optical properties were investigated, and it was found that CaO was more effective with respect to inhibiting grain growth than MgO, but not as effective as MgOs in promoting densification.
Journal ArticleDOI
MgO assisted densification of highly transparent YAG ceramics and their microstructural evolution
Tianyuan Zhou,Le Zhang,Le Zhang,Wei Shuai,Lixi Wang,Hao Yang,Zhenxiao Fu,Hao Chen,Farida Selim,Qitu Zhang +9 more
TL;DR: In this article, the microstructure evolution and optical property of as-fabricated transparent YAG ceramics as a function of MgO doping concentration were systematically investigated, and it was shown that a small amount of doping could effectively promote densification and grain growth of YAG, when the sintering temperature was lower than 1660°C, and dramatically accelerate its grain growth between 1540°C and 1660
Journal ArticleDOI
Enhanced light extraction of single-surface textured YAG:Ce transparent ceramics for high power white LEDs
Le Zhang,Le Zhang,Le Zhang,Sun Bingheng,Gu Lingcheng,Wei Bu,Xian-Zhu Fu,Rong Sun,Tianyuan Zhou,Tianyuan Zhou,Farida Selim,Ching-Ping Wong,Hao Chen +12 more
TL;DR: In this article, a planar YAG:Ce transparent ceramics with different surface textures, thicknesses and assembly modes with high power LED chips were designed to enhance the light extraction.
