摘要

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 deg C) and in a very short time (<5 min). Thus, this review starts with combustion synthesis followed by luminescent properties of combustion synthesized tricolor 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 centre dot 6Al_2O_3 are studied. In the case of green phosphors, co-doping of Eu~(2+), Ce~(3+) andTb~(3+) in LaMgAl-(11)O_(19) is investigated.
