چکیده انگلیسی
Green emitting Li2Mg1âxZrO4:xTb3+ (0.1â¯â¤â¯xâ¯â¤â¯2.0) phosphor powders were synthesized via the wet chemical synthesis and the luminescent proprieties were studied when excited at 380â¯nm and present a dominant and strong green luminescence peak at 543â¯nm, due to D-F transition. The preparation of Li2Mg1âxZrO4:xTb3+ (0.1â¯â¤â¯xâ¯â¤â¯2.0) phosphor powders were confirmed by X-ray diffraction (XRD) results without any secondary or impurity phases. The size and morphology of the Li2Mg1âxZrO4:xTb3+ (0.1â¯â¤â¯xâ¯â¤â¯2.0) phosphor powders were further examined by scanning electron microscopy (SEM). Photoluminescence (PL) results have shown strongest green emission at 543â¯nm, which is originated due to 5D4-7F5 transition of Tb3+ ion, for the Li2Mg1âxZrO4:xTb3+ (0.1â¯â¤â¯xâ¯â¤â¯2.0) phosphor. The addition of concentration Tb3+ was greatly improved the photoluminescence properties of present phosphors. The present study suggests that the Li2Mg1âxZrO4:xTb3+ (0.1â¯â¤â¯xâ¯â¤â¯2.0) phosphor is a strong candidate as a green component for phosphor-converted white light-emitting diodes (LEDs).
