Sorry, I accidentally added another article. Here is article about the nanoscintillator material.

Ian Nieves

Some work has also been done to develop nanostructured EuS-based scintillators. This effort was spearheaded by Physicist Jay Dickerson at Vanderbilt University.

Thank you for this information.

Anant Singhal

My professor, Dr Hawari would be a good person to contact regarding this topic. http://ncsu.edu/nano/faculty/profiles/details.php/19

He is definitely involved in work on this topic.
