Objective

In nowadays state-of-the-art PET scanners gadoliniumsilicate (GSO) or lutetiumsilicate (LSO) single crystals doped with light emitting Ce3+ ions are used for detection of the high energy photons. The STRING project aims at developing ceramic scintillators with faster emission, higher conversion efficiency and reduced production costs. Such scintillators further improve the image quality at lower costs.
 


Firstly the luminescence of Pr3+ and Nd3+ will be explored in a variety of host lattices to obtain new and faster scintillator materials. Next to that research will be done to understand and reduce the time for initial build-up of the emission intensity.

It will also be investigated whether the costly process of single crystal growth can be replaced by the significantly cheaper production of highly transparent ceramic scintillators via sintering of polycrystalline powders under high pressures and at high temperatures.

The project addresses many different capabilities and disciplines. Each of the partners of the consortium contributes to one or more of the capabilities and disciplines needed.
