| Outline of Final Research Achievements |
In order to develop a scintillator with fast decay and high emission intensity, we have investigated new Auger-free luminescence (AFL) mainly for A2ZnCl4(A=Rb,K) crystal as a novel scintillator material, and evaluated their basic physical properties. Luminescence lifetime evaluation, which is important as characteristic evaluation of device development, was carried out by using vacuum ultraviolet light pulses under single bunch operation and time correlated single photon counting method in the Institute for Molecular Science. In this study, we found a new type of AFLs due to interatomic p-d transitions, and analyzed their decay curves. From our experimental results, both sides of fundamental and applied physics of AFL are considered.
