中法核工程与技术学院第90期学术午餐会
90th Academic Lunch Seminar of Sino-French Institute of Nuclear Engineering and Technology
Topic:Noncontact optical thermometer based on rare earth ion doped materials
Speaker: Dr. XING Lili
Time: 12:40 – 14:00, Friday October 19, 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:
Optical temperature sensors based on the fluorescence intensity ratio (FIR) technique are significantly stimulated by the demands for noncontact, safe, cheap and reliable sensors in monitoring the temperatures of harsh environments. Generally, the fluorescence of lanthanide ion can be produced by upconversion process, and it is well known that the upconversion fluorescence technique is well-suited to optical temperature sensor owing to its low cost of pump laser and absence of stray light. Herein, rare earth ion doped upconversion material and its applications will be introduced. Furthermore, the temperature sensing properties are put forward.
About the speaker:
Dr. Xing Lili, lecture of IFCEN, received her Ph.D. degree in Harbin Institute of Technology, joined in IFCEN in 2014. Her research is focused on the preparation of rare earth ions doped single crystal, nanocrystal and glass ceramic, explore their applications in the fields of display, solar cell, and optical temperature measurement.
