By combining the unique features of the quantum cutting luminescence and long persistent luminescence, we design a new concept called "near-infrared quantum cutting long persistent luminescence (NQPL)", which makes it possible for us to obtain highly efficient (>100%) near-infrared long persistent luminescence in theory. Guided by the NQPL concept, we(More)
Un-doped Sr3Al2OCl2 material is synthesized by conventional solid state method in reducing atmosphere. It shows intense photostimulated luminescence and the emission band of spectrum covers in 420-800 nm under infrared laser (980 nm) stimulation. Both the emission centers and traps are related to oxygen-deficient defects. Moreover, thermoluminescence(More)
