Europium doped LaMgAl 11 O 19 phosphor was prepared by the combustion method. The as-prepared and post-treated (1350°C 10h 5% H 2 +95% N 2 ) phosphors were investigated by X-ray diffraction (XRD), Fourier transform infrared (FT-IR), scanning electron microscopy (SEM), photoluminescence (PL) and electron paramagnetic resonance (EPR) techniques. XRD patterns show that...
ZnAl 2 O 4 :Mn green light emitting powder phosphors have been prepared by urea combustion technique involving furnace temperatures about 500°C in a short time (<5min). The prepared powders were characterized by X-ray diffraction, scanning electron microscopy, Fourier-transform infrared spectrometry and the surface area measurements by a Brunauer–Emmet–Teller (BET) adsorption isotherms...
