0D defects in isostructural Zn-based single crystals
Original language description
One of the potentially possible applications of zinc oxide as well as caesium lead bromide is time-of-flight (TOF) positron emission tomography (PET). Therefore, the timing and light yield of a scintillating detector are very important. Strong excitonic luminescence with the decay time around 400-500 ps has been measured in ZnO nanoparticles. CsPbBr3 nanoparticles also have very fast (about 300 ps) and strong excitonic luminescence. A ZnO/CsPbBr3 core/shell heterostructure exhibited remarkable enhancement of photoluminescence intensity (17 times). This can be potentially applicable in the TOFPET scintillating detector. The factors influencing photophysics of luminescent materials are in most cases 0D defects (point defects) of different origin. To understand their influence on the ZnO/CsPbBr3 heterostructures, the ZnO substrate should be investigated first. Note, that the influence of the Zn- or O-face along the <0001> axis or the Zn and O mixture along the <1010> (or similar) axis on the X-ray induced 0D defects is not known in ZnO. Therefore, this is the aim of the present research. Moreover, to understand the role of oxygen, it was replaced by Se and Cr doping was applied.
