Abstract
- Pechini method has been applied for synthesis of the phosphates in the submicro-state. Dimensions of the obtained grains by this method fall into the 100-1000 nm range. The following samples have been synthesised: stoichiometric orthophosphate Na 3 Ce(PO 4 ) 2 and metaphosphate NaCe(PO 3 ) 4 both doped with 2 and 5% of Eu 3+ . Optical absorption and emission studies have been performed to characterise the properties and structure of the compounds studied. The electronic characteristics of the Ce 3+ and Eu 3+ ions in these materials have been discussed.
