图16 VUV-UV光谱研究的CaSi10-nAl2+nOnN16-n:xEu2+材料的持续发光特性[61]

Fig. 16 Persistent luminescence properties of CaSi10-nAl2+nOnN16-n:xEu2+ material studied by VUV-UV spectra[61] (a) Excitation and (b) emission spectra of CaSi10Al2N16: xEu (x = 0.1%-8%) samples with inset showing the integral intensity (blue curve) and the Stokes shift (red curve) of those samples against Eu concentration (the sharp peaks in the range of 400-500 nm being caused by the Xe lamp equipped in the FLS 920 spectrophotometer); (c) Emission spectra of CaSi10-nAl2+nOnN16-n: 0.5%Eu (n=0-1) samples with inset showing the integral intensity versus n values (colorful figures are avaailable on websites)
