Optical characteristics and energy transfer analysis of Dy3+-Pr3+ ions doped in CeF3 crystal J. Lumin. (IF 3.6) Pub Date : 2024-03-08 Guoliang Deng, Yilun Yang, Min Xu, Qiannan Fang, Shanming Li, Chengchun Zhao, Yin Hang
The Dy,Pr:CeF single crystal was successfully grown and its optical characteristics were investigated systematically. The analysis of energy transfer process between Dy and Pr in CeF crystal was also carried out. The XRD study shows the crystal belongs to the hexagonal crystal system and its lattice parameters are a = 7.1252 Å and c = 7.2775 Å. The maximum phonon energy of the crystal was speculated

Preparation of Er3+, Ho3+, Yb3+-doped Bi2WO6 upconversion luminescent materials and their temperature sensing properties J. Lumin. (IF 3.6) Pub Date : 2024-03-08 Munire Maimaiti, Linxiang Wang, Mengliang Jiang, Xin Feng, Yan Zhang
A high-temperature solid-phase method was used to prepare codoped BiWO upconversion luminescent materials with different concentrations of Er, Ho, and Yb. The microstructure, upconversion luminescence and temperature sensing properties of the synthesized powders were analyzed. X-ray diffraction (XRD) patterns showed that the doping of Er, Ho, and Yb did not affect the orthorhombic crystal structure

Tunable white light emission in antimony doped vacancy-ordered double perovskite Cs2ZrCl6 nanocrystals J. Lumin. (IF 3.6) Pub Date : 2024-03-07 Dengbang Zhao, Ying Liu, Yanbing Han, Xu Chen, Mochen Jia, Jibin Zhang, Linyuan Lian, Di Wu, Xinjian Li, Zhifeng Shi
Design of stable white-light emitting materials based on the emerging lead-free metal halide colloidal nanocrystals is in urgent demand for lighting technology innovation. Herein, we developed a facile hot-injection method and optimize the synthesis conditions to prepare Sb doped CsZrCl nanocrystals with good uniformity and crystallinity. Sb ions were doped into the CsZrCl lattice and proved to occupy
