Xu Shuping graduated from College of Chemistry, Jilin University in 2001, achieving a bachelor's degree. In June 2006, she obtained her Ph.D. in Science, Jilin University, specializing in physical chemistry. In June-Dec. 2004, she visited Ozaki (Ozaki Yukihiro) research group of Kwansei-Gakuin University, Japan, as a visiting student, mainly engaged in the research of surface-enhanced Raman spectroscopy. Since 2006, she worked at Institute of Theoretical Chemistry, Jilin University. Within Feb. 2007 - July 2008, she joined in Juila Xiaojun Zhao research team, Department of Chemistry of North Dakota University for postdoctoral research, mainly engaged in the preparation of silica / metal nanomaterials for fluorescence enhancement. Since Sep. 2013, she was employed as a professor in the major of Physical Chemistry. She hosted 3 National Natural Science Foundation of China (NSFC), 2 fund of Ministry of Education of China. As the main participants, Dr. Xu was involved in NSFC major research program and special funds for scientific instrument development of NSFC and NIP. Dr. Xu has published more than 90 papers and 3 patents have been authorized.

The main interest is on surface-enhanced spectroscopy, specifically, involving three focuses: (1) Supramolecular assembling of metal nanoparticles for surface enhanced spectroscopy, photocatalysis, biosensing . (2) Development of periodical plasmonic nanostructures and devices for directional emission of SERS and fluorescence. (3) Design and fabrication of luminescent nanoparticles for bioimaging, nanolabels, and chemical sensing.

会议报告主题/Topic:
Angle-dependent spectroscopy for directional SERS emission

摘要/Abstract:
In this talk, I will present recent progress on the technologies and equipments of angle-dependent or angle-resolved spectroscopy in our group. The instrumental configuration will be shown and their working ways will be explained. They are used for the studies of plasmon-enhanced spectroscopies, including directional emission of surface-enhanced Raman scattering, waveguide-coupled plasmon for SERS, and surface plasmon-coupled emission etc. The optimization of incident angles and collection angles works for the purpose of the improvement of excitation and collection efficiencies and further for the stronger signal.
