Title : Biomedical applications of light emission from thin film nanomaterials


Rare-Earth (RE) doped nitride semiconductors thin film nanomaterials are attracting increasing attention as phosphor materials, and are used for optical displays and devices. Sputter deposited AlN has been shown to be a viable host for luminescent rare earth (RE) ions due to its transparency over a wide range, including the UV, IR, and entire visible range. GaN doped with RE ions elements is also used for similar applications in visible and IR. The potential suitability and use of luminescence from RE elements towards biomedical applications has shifted the paradigm of RE applications. The present work reports electron penetration depth for electron beam therapy applications and stopping power calculation exploiting the luminescence from thin film AlN:Thulium and AlN:Holmium thin film nanomaterials. A new method of calculating electron stopping power of materials used for radiation shielding and protection is introduced based upon the blue and green light emission from AlN:Tm/AlN:Ho bilayers. This method also provides a simple way of testing electron beam for energy loss with time. The current work also report biomedical applications of RE- Oxide nanoparticles and the use of GaN use a protector from ultraviolet (UV) radiation. The potential use of gadolinium thin films to make a single radiation detector for α-, β-, and γ- radiations detection. Triply ionized Gd+3 is a strong UV emitter. It has been proved already that UV light is emitted from AlN:Gd thin film nanomaterials under photon and electron excitations which can be used to detect β- and γ-ray photons.

Audience take away:

•    The audience will learn how light emission from rare-earth based nanomaterials can be used for biomedical applications.
•    The audience will also learn how they can develop experimental set-up and work to perform on similar projects.
•   Study and investigations of biomedical applications of light emission from rare-earth nanomaterials will provide a great help to audience in their job, particularly in an environment where facilities are available to make and test their own thin film nanomaterials. Researchers can work on a number of combinations, bilayers, and target applications to build their research work. It will help researchers to bring physics, materials science and biology together for more practical and unique applications in health care.


I am Dr. Muhammad Maqbool an Associate Professor of Physics & Health Physics at the University of Alabama at Birmingham (UAB). I also worked as an Associate Professor of Physics at Ball State University, Indiana for 9 years. I got my Ph.D degree in Physics from Ohio University, USA, in 2005. I have published over 6 dozen peer-reviewed research paper and book chapters in the areas of Condensed Matter Physics, Nanomaterials, Photonics, Health Physics and Biophotonics. In 2016 I was awarded US Patent for my invention of a Titanium infrared microlaser on optical fiber.
