Preparation and Photoluminescence of Nano-Sized Green Phosphors by Solution Combustion Synthesis

Abstract:

By adopting a facile solution combustion synthesis (SCS) method, pure well-crystallized (Ba,Sr)MgAl₁₀O₁₇:Mn green phosphors were successfully prepared. The crystallinity, particle size, morphology, and luminescent properties were characterized by XRD, FE-SEM and spectrofluorometer respectively. The results indicated that the obtained phosphors have spherical morphology, good crystallinity, and strong green emission. The emission spectra of obtained nanophosphor on 147nm excitation consist of a wide band with the peak at 518nm, which corresponds to the transition from the 3d⁵(⁴T_1g) excited state to the 3d⁵(⁶A_1g) ground state of Mn2+. The synthesized phosphors can be efficiently excited at VUV light and have potential application in Plasma Display Panels (PDPs), 3D displays and mercury-free fluorescent lamps
