AB - Rare-earth niobates, LnNbO4 (Ln = Y, La, Gd) are well-known self-activated phosphors due to charge transfer inNbO43 showing a broad and strong emission band in the spectral region around 410 nm. In order to find new blue and redphosphors for FED, LaNbO4 : X (X = Bi, Eu) phosphors are prepared through solid-state reactions at high temperature.at 1250oC for 2 h followed by second firing at 1400oC for 1 h. Under irradiation at 254 nm, 1 mol% Bi3+ doped LaNbO4phosphor shows strong blue emission band with a range of 420~450 nm. Also 10 mol% Eu3+ doped LaNbO4 phosphorshows the maximum emission intensity at about 610 nm. Emission peaks at 415~460 nm, 530~560 nm and 570~620 nm areobserved in phosphors below 10 mol% Eu3+ doped LaNbO4. Similar results are obtained in cathodoluminescent property ofthese phosphors.Key words Low voltage cathodoluminescent, Photoluminescent, Lanthanide niobates, FED, Solid state reaction, Phosphor,Excitation spectrum, Emission spectrumLaNbO4 : X (X = Bi, Eu) .... .. . . .. ... .. ....... ...†..... .... ... , ...... ... , .. , 330-714(2005. 10. 5. .. )(2005. 12. 27. .... ). . .... niobates.
