Temperature and concentration dependent Judd-Ofelt analysis of Y2O3:Eu3+ and YVO4:Eu3+
(Physica B: Condensed Matter, 2020)
Judd-Ofelt analysis has been performed from the photoluminescence emission spectra of Y2O3:Eu3+ with 3%, 1% and 0.1% doping concentration and YVO4:Eu3+ with 1% doping concentration, in temperature range from 40 °C to 460 ...
Gamma-radiation effects on luminescence properties of Eu 3+ activated LaPO 4 phosphor
(Nuclear Instruments and Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, 2018)
Eu3+ activated LaPO4 phosphors were prepared by a high-temperature solid-state method and irradiated to different high-doses gamma-radiation in the 0-4 MGy range. No effects of high-doses of high-energy radiation on ...
Luminescence Intensity Ratio thermometry and Judd-Ofelt analysis of TiO2:Eu3+
(Optical Materials, 2018)
Luminescence thermometry on europium doped TiO2 films, prepared by the plasma electrolytic oxidation, was investigated by the Luminescence Intensity Ratio method. The performance of the material for temperature sensing was ...
Judd-Ofelt and chromaticity analysis of hafnia doped with trivalent europium as a potential white LED phosphor
(Optical Materials, 2019)
Judd-Ofelt analysis of HfO2:Eu3+ with various europium doping concentrations, formed by plasma electrolytic oxidation, had been investigated. Ω2 parameter is increasing, while Ω4 parameter shows no concentration dependence. ...
Judd-Ofelt parametrization from emission spectra: The case study of the Eu3+ 5D1 emitting level
(Chemical Physics, 2020)
Traditional applications of the Judd-Ofelt (JO) theory to the analysis of the Eu3+ optical spectra make use of the emission transitions originating from the 5D0 manifold. In the present paper, we report an alternative ...
