Scintillators play a key role in the detection chain of several applications which rely on use ionizing radiation, and it is often mandatory to extract detect generated scintillation light as efficiently possible. Typical inorganic scintillators do however feature high index refraction, impacts extraction efficiency negative way. Furthermore, such preclinical Positron Emission Tomography (PET) ...
