This article presents the analysis of advanced Er3+/Yb3+: Na3Zr2(SiO4)(2)PO4 (NASICON) monoclinic phosphors prepared by solid state reaction technique as upconverting materials. The structural parameters, surface morphology, and optical characteristics of the synthesized phosphors are analyzed. The codoping of Yb3+ ions in the Er3+ doped phosphors exhibit fascinating results under 980 nm continuous wave diode laser excitation, which can be used for thermometry based on fluorescence intensity ratio (FIR).
The advanced new Er3+/Yb3+: Na3Zr2(SiO4)(2)PO4 (NASICON) monoclinic phosphors prepared by solid state reaction technique has been analyzed as upconverting materials. The crystal phase, structural parameters, surface morphology, different functional groups and bandgap of the synthesized phosphors have been analyzed. Under 980 nm continuous wave diode laser excitation, the codoping of Yb3+ ions in the Er3+ doped phosphors exhibit fascinating results. Stark sublevels observed in the upconversion emission have been used for the fluorescence intensity ratio (FIR) based thermometry. Relative & absolute sensitivity, thermal stability and temperature dependent CIE have been determined. The thermally stable Na3Zr2(SiO4)(2)PO4: Er3+/Yb-3 phosphors with high color purity can be utilized in sensing, display and security purposes. (c) 2022 Elsevier B.V. All rights reserved.
