The photoluminescence spectra were recorded on a FP8500 spectrophotometer (JASCO Co., Ltd.) with the excitation wavelength at 365 nm (atmosphere: air, excitationslit/detection-slit: 2 nm/2 nm, measure time: 0.1 s, step width: 1.0 nm, sample weight: 150 mg, and shape: pellet), and the detection was used by photomultiplier tube.
