Abstract

This review article is intended to show feasibility of solution combustion process for the synthesis of rare-earth activated insulating materials at low temperature (350-500 degrees C) and in a very shorttime (< 5 min). Thus, this review starts with combustion synthesis followed by luminescent properties of combustion synthesized tricolour lamp phosphors. Major focuses in red phosphors are effect of calcinations and of impurities on luminescence of $Eu^{3+}$ activated red phosphors. In the $Eu^{2+}$ activated blue phosphor section, effect of activator concentration $(Eu^{2+})$ and concentration of BaO in $BaO.6Al_{2}O_{3}$ are studied. In the case of green phosphors, co-doping of $Eu^{2+}$, $Ce^{3+}$ and $Tb^{3+}$ in $LaMgAl_{11}O_{19}$ is investigated.
