Strong anti-Stokes photoluminescence from colloidal ytterbium-doped yttrium lithium fluoride nanoparticles.


We have successfully synthesized colloidal  lithium yttrium fluoride (YLF) nanoparticles doped with ytterbium with the goal of investigating their anti-Stokes emission. The Yb content was varied between 1% and 10%. The nanoparticles emit in near-infrared, with the emission spectrum extending from 960 nm to 1060 nm when excited with the 900 nm light. Strong anti-Stokes photoluminescence was observed when using excitation wavelengths ranging from 1000 nm to 1020 nm.


I am a PhD student in Optical Science and Engineering program in the department of Center for High Technology Materials. I have background in physics, chemistry, and mathematics. My research area of interests are spectroscopy, nanotechnology, synthesis & characterization of nanoparticles and quantum dots of various materials. I am currently researching the optical properties of different types of rare earth-doped YLF nanoparticles for laser cooling applications.

About the Poster Showcase:  

In the poster session, graduate students from programs across campus displayed their research in poster format and engage directly with conference attendees and fellow scholars. Research posters come in a wide variety of topics, crossing fields throughout the humanities and sciences. Poster evaluators are also on hand to provide feedback to presenters. Students are nominated by their academic program to display a research poster at the conference.

This year's Poster Showcase took place on Thursday, November 10th from 11:00 AM - 1:00 PM in the PAIS hallways. Finalists from the LoboBITES competition gave their presentations from 4:30 PM - 5:30 PM in the PAIS Auditorium. The Reception was from 5:30 PM - 6:30 PM in the lobby of PAIS.
