| 内容記述タイプ | Abstract | |||||
| 内容記述 | X-ray fluorescence analysis based on electron channeling effects in transmission electron microscopy (TEM) was performed on Ca2SnO4 phosphor materials doped with Eu^3+/Y^3+ at various concentrations, which showed red photoluminescence associated with the 5D0–7F2 electric dipole transition of Eu^3+ ions. The method provided direct information on which host element site dopant elements occupy, the results of which were compared with those of X-ray diffraction (XRD)–Rietveld analysis. The obtained results indicated that while it is not favorable for a part of Eu^3+ to occupy the smaller Sn^4+ site, this is still energetically better than creating Ca vacancies or any other of the possible charge balance mechanisms. The local lattice distortions associated with dopant impurities with different ionic radii were also examined by TEM–electron energy-loss spectroscopy (TEM–EELS). The change in PL intensity as a function of dopant concentration is discussed based on the experimental results, although the general concept of concentration quenching applies. | |||||
