Dysprosium-Containing Nanocrystals for Thermal Neutron Detection
We propose a novel concept of optical detection of thermal neutrons in a passive device that exploits transmutation of Dy-164, a dominant, naturally occurring isotope of dysprosium, into a stable isotope of ei...

Optimization of Ce Content in CexLa1-xF3 Colloidal Nanocrystals for Gamma Radiation Detection
We report on experimental investigations of CexLa1-xF3 colloidal nanocrystals (CNCs) and their properties in function of Ce content. The CNCs were characterized by TEM, energy-dispersive X-ray spectroscopy (EDS),...

Colloidal Synthesis and Characterization of Optically Active ZnO/ZnS Core/Shell Nanocrystals
ZnO colloidal nanocrystals have been synthesized using two different approaches and characterized by HRTEM, EDS, and photoluminescence spectroscopy. ZnO nanocrystals synthesized from zinc alkoxy alkyl precurso...

Effects of Gamma Irradiation on Optical Properties of Colloidal Nanocrystals
The effects of 137Cs gamma irradiation on photoluminescence properties, such as spectra, light output, and lifetime, of several types of colloidal nanocrystals have been investigated. Irradiation-induced damage t...
