Highly luminescent ZnO:Ga-polystyrene composite (ZnO:Ga-PS) with ultrafast subnanosecond decay was prepared by homogeneous embedding the ZnO:Ga scintillating powder into organic matrix. The photo-induced precipitation subsequent calcination in air and Ar/H2 atmospheres. subsequently mixing polystyrene (10 wt% fraction of ZnO:Ga) press compacted to 1 mm thick pellet. Luminescent spectral kinetic characteristics were preserved. Radioluminescence spectra corresponded purely phase emission at...
Fast emitting polymeric scintillators are requested in advanced applications where high speed detectors with a large signal-to-noise ratio needed. However, their low density implies weak stopping power of energy radiation and thus limited light output sensitivity. To enhance performance, can be loaded dense nanoparticles (NPs). We investigate the properties series by means photoluminescence scintillation spectroscopy, comparing standard composite system hafnium dioxide (HfO2) NPs. The...
The discovery of scintillation in the blue regime from poly(ethylene naphthalate) (PEN), a commonly used high-performance industrial polyester plastic, has sparked interest physics community as new type plastic scintillator material. This observation addition to its good mechanical and radiopurity properties makes PEN an attractive candidate active structure for low-background experiments. paper reports on investigations potential terms production tests custom made tiles various light output...
Heat treatment is needed to increase the luminescence intensity of ZnO:Ga particles, but it comes at cost higher particle agglomeration.
