Chen Publishes 3 Papers with Alumni, Richardson

Dr. Jixin Chen recently published three papers—on bioimaging in the near-infrared region, promising materials for photovoltaics and optoelectronics, and a new thermal imaging technique to measure the temperature profile of a thin film—with graduate students from Ohio University and colleagues from around the world.

Chen, associate professor of Chemistry & Biochemistry, is also a member of the Nanoscale & Quantum Phenomena Institute.

Bioimaging in the near-infrared window is of great importance to study the dynamic processes in vivo with deep penetration, high spatiotemporal resolution, and minimal tissue absorption, scattering, and autofluorescence. In a paper in ACS Applied Bio Materials, researchers study polymer dots for bioimaging at the near-infrared region. Chen collaborated with Prof. Yang-Hsiang Chan and others from National Chiao Tung University, Taiwan.

Mixed-halide lead perovskites (MHPs) are promising materials for photovoltaics and optoelectronics due to their highly tunable band gaps. However, they phase segregate under continuous illumination or an electric field, the mechanism of which is still under debate.

The fast phase segregation and remixing of mixed halid lead perovskite is measured in Chen’s goup with time resolution of tens of millisecond in a paper in the Journal of Physical Chemistry Letters. The lead author is OHIO alumnus Dr. Juvinch R. Vicente (’20 Ph.D. Chemistry).

In collaborattion with Dr. Hugh Richardson’s group at Ohio University, Chen and co-authors developed a new thermal imaging technique to measure the temperature profile of a thin film coated with a thin layer of temperature sensing material.

OHIO co-authors included lead author and graduate student Kristina Shrestha and alumni Vicente and Dr. Ali Rafiei Miandashti (’19 Ph.D. Chemistry).
