Luminescence of praseodymium doped perovskite - like SrLa₄Ti₅O₁₇ under excitation with VUV and UV synchrotron radiation
The wide-band complex spectra of intrinsic luminescence of undoped SrLa₄Ti₅O₁₇ compounds are found in range of 350-1100 nm under excitation by the light from ultraviolet and vacuum ultraviolet range (50-334 nm) of synhrotron radiation. The possible origines of the observed luminescence are associate...
