Abstract

Nano-sized crystals were obtained for both (Y0.95Eu0.05)2O3 phosphor and Co2Z ferrite (Ba3Co2Fe24O41) GHz noise absorber by the respective gel-combustion reactions, Nitrate aqueous mixtures were gelated by heating in a presence of glycine. (Y0.95Eu0.05)2O3 phosphor with crystallite size of 43nm was prepared from the glycine gel ignited at 300℃. For Co2Z ferrite preparation, use of Fe(acac)3 as an iron source was effective to obtain its nanocrystals in lower firing temperature of 1000℃ than that in solid state reaction.
