GLOBAL BIODEFENSE – A University of Texas at Arlington research team says recently identified radiation detection properties of a light-emitting nanostructure built in their lab could open doors for homeland security and medical advances. In a paper to be published in the Oct. 1 issue of Optics Letters, UT Arlington Physics Professor Wei Chen and his co-authors describe a new method to fabricate transparent nanoscintillators, a material that glows in response to radiation, by heating nanoparticles composed of lanthanum, yttrium and oxygen until a transparent ceramic is formed.
