The enhancement of emission intensity and enlargement of color gamut by a simple local structure substitution with highly thermal stability preserved
(Optical Materials, 2019)
The local crystal structure engineering becomes an important strategy to design new phosphors with enhanced optical and thermal performance of white light-emitting diodes. Herein, a series of Na3Sc2(PO4)3: Eu2+ and ...
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. ...
Li1.8Na0.2TiO3:Mn4+: The highly sensitive probe for the low-temperature lifetime-based luminescence thermometry
(Optics Communications, 2019)
In this work, the potential of Li1.8Na0.2TiO3:Mn4+ for the lifetime-based luminescence thermometry is assessed. The material is prepared by the solid-state reaction of Li2CO3, Na2CO3, and nanostructured TiO2 at 800 °C, and ...
