| 内容記述 | An idea for developing scintillators possessing both a large light output and a quick response is presented. Usually, some direct-gap semiconductors exhibit sub-nanosecond decaying ultra-fast scintillation only at a very low temperature. The authors found that the thermal quenching is effectively prevented by a construction of a low-dimensional quantum confinement system, and practical light output can be obtained even at room temperature. A comparative study in scintillation properties of two- and three-dimensional semiconducting materials having similar compositions was demonstrated, and physical effects of the quantum confinement systems are discussed. A crystals of (C6H13NH3)2PbI4 having a multiple quantum well structure exhibited three decay components of 390 ps, 3.8 ns and 16 ns with the ratios of 28%, 29% and 43%, respectively. And the total light output at 300 K was 11% of that of NaI:Tl. |
