Er3+/Yb3+ codoped phosphor Ba3Y4O9 with intense red upconversion emission and optical temperature sensing behavior
Hao Wu,Zhendong Hao,Liangliang Zhang,Xia Zhang,Yu Xiao,Guohui Pan,Huajun Wu,Yongshi Luo,Ligong Zhang,Zhang Jiahua +9 more
TL;DR: The Ba3Y4O9 host matrix with a low cutoff phonon energy of 585 cm−1 is first applied to upconversion (UC) luminescence (UCL) by codoping Er3+/Yb3+. The new phosphor shows an intense red UC emission which is 6.8-fold and 5.9-fold stronger than that of Y2O3 and β-NaYF4, respectively, under 980 nm GaAs laser diode excitation at a low density.
Journal ArticleDOI
Highly Efficient Green-Emitting Phosphors Ba2Y5B5O17 with Low Thermal Quenching Due to Fast Energy Transfer from Ce3+ to Tb3.
Yu Xiao,Zhendong Hao,Liangliang Zhang,Wenge Xiao,Dan Wu,Xia Zhang,Guohui Pan,Yongshi Luo,Jiahua Zhang +8 more
TL;DR: The green phosphor shows attractive performance for near-UV-based white-light-emitting diodes applications and is attributed to suppression of Ce3+ thermal de-excitation through fast energy transfer to Tb3+, which in the green-emmitting excited states is highly thermally stable such that no lifetime shortening is observed with raising temperature to 210 °C.
