    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...
