Project title: Fast emitting oxide scintillators 
Researcher: 
Irene Carrasco Ruiz
Supervisor: Marco Bettinelli,Co-supervisor:Martin Nikl


Project description

Objectives:
To synthesize new undoped and Pr- and Nd-doped complex phosphates and silicates as nanopowders and conventional powders, with the aim of obtaining new scintillator materials.
To characterize their structural, optical, luminescence and scintillation characteristics
To find out relation between chemical composition of the host, the properties measured, technology-specific material defects and scintillation performance/application potential

Tasks and methodology:
Preparation of materials in the project (UNIVR).
Characterization by the absorption and time-resolved luminescence spectroscopies, thermoluminescence, electron paramagnetic resonance (EPR).
Evaluation of correlated experiments. Fellow will participate in all the performed experiments and will make all related data evaluation.


Secondments: Institute of Physics AS CR Prague, Czech Republic; Tartu University, Tartu, Estonia.
