中法核工程与技术学院第86期学术午餐会

86^th Academic Lunch Seminar of Sino-French Institute of Nuclear Engineering and Technology

Topic: Automatic crystal growth and X-ray excited persistent luminescence in LiNbO₃ single crystal

 Speaker: Dr. Lin Shaopeng

 Time: 12:40 – 14:00, Friday September 14, 2018

 Venue: F309 in the teaching building, Zhuhai Campus, SYSU

 Organizer: Sino-French Institute of Nuclear Engineering and Technology,  Sun Yat-sen University

 Language: English

 Abstract:

 The design and implementation of an automatic crystal growth system will be introduced. Pr³⁺ single doped and Pr³⁺ and   Mg²⁺ co-doped       congruent LiNbO₃ (CLN) single crystals were grown using the crystal growth system. For the first time, persistent luminescence (PersL) was found     in Pr³⁺ and Mg²⁺ co-doped CLN excited by ultraviolet and X-ray. A serial of  experiments have been performed to explore the mechanism of PersL   and the Mg2+ ion wasproved to play a key role.
