| Abstract: | Twenty one doped SrAl2O4 long after-glowed phosphors with 4 series were synthesized by self-propagating high-temperature synthesis method (SHS) with urea-nitrate solution which served as media at 600 degrees C. They are SrAl2O4: Eu(2+)0.012 5, RE(3+)0.012 5 (RE(3+) = Ce(3+), Pr(3+), Nd(3+), Tb(3+), Dy(3+)), SrAl2O4 : Eu(2+)0.012 5, M0.012 5 (M = Li(+), Be(2+), Cd(2+), Mn(2+), Cu(2+), Ag(+), Zn(2+), Pb(2+)), SrAl2O4 : Eu(2+)0.012 5, Dy(3+)0.012 5, M0.012 5 (M = Mn(2+), Cu(2+), Ag(+), Zn(2+)), and SrAlO4 = Eu(2+)0.012 5, Dy(3+)0.012 5, RE(3+)0.012 5 (RE(3+) = Ce(3+), Pr(3+), Nd(3+), Tb(3+)), of which luminescence and after-glowing features were tested. The morphology of all these samples presents a state of porosity and laxity. The samples show an intense emission peak at 514 nm and broad peaks of the excitation spectra at 290-360 nm, Tb(3+) and Dy(3+) had most effects on luminance and after-glowed time respectively. The SrAl2O4 : Eu(2+)0.012 5, Dy(3+)0.012 5 had good luminance and proper after-glowed time as well. |
