    Luminescence Thermometry Based on the Upconversion Luminescence from the Stark Sublevels of BaY2F8:Yb3+, Tm3+ Phosphor

    Visible and near-infrared (NIR) upconversion luminescence (UCL) emissions originating from the BaY2F8: Yb3+, Tm3+ systems were investigated under a laser excitation at 980 nm. The BaY2F8:20 mol% Yb3+, x mol% Tm3+

    White Light Emitting MZr4(PO4)6:Dy3+ (M = Ca, Sr, Ba) Phosphors for WLEDs

    A series of MZr4(PO4)6:Dy3+ (M = Ca, Sr, Ba) phosphors were prepared by the solid state diffusion method. Confirmation of the phase formation and morphological studies were performed by X-ray powder diffraction (...

    Photoluminescence properties of Eu3+/ Sm3+ activated CaZr4(PO4)6 phosphors

    Solid state reaction method was employed for the synthesis of a series of CaZr4(PO4)6: Eu3+/Sm3+ phosphors. The red-emitting CaZr4(PO4)6:Eu3+ phosphors can be efficiently excited at 396 nm and thereby, exhibit a ...
