Scientists have made a significant breakthrough in understanding the properties of a type of crystal called BaF2- LaF3, which has potential applications in fast scintillators for medical imaging and particle physics.
The researchers used a powerful technique called synchrotron radiation to excite the crystals and study their luminescent properties. They found that the crystals emit light with an extremely short decay time constant of just 150 picoseconds, making them promising candidates for use in fast scintillators.
One of the key findings is that the luminescence is due to a novel radiative recombination process between electrons and holes in the core bands of the Ba2+ and La3+ ions. This process is faster than previously thought possible, and it’s not yet fully understood.
The researchers also used ab initio calculations to study the electronic structure of the crystals and found that the energy levels of the core bands facilitate the rapid recombination process. These findings have important implications for our understanding of the behavior of electrons in solids.
The discovery has significant potential applications in fields such as medical imaging, where fast scintillators could improve the accuracy and speed of diagnoses. It also opens up new avenues for research into the properties of materials at the atomic level.
Overall, this study provides a major step forward in our understanding of the properties of BaF2- LaF3 crystals and their potential applications. Further research is needed to fully understand the mechanisms behind the rapid luminescence, but these findings have significant implications for a range of fields.
