Abstract
Lanthanum phosphate (LaPO4) belongs to the family of rare earth phosphates characterized as a fluorescence material. Europium ion is known for its orange –red fluorescence. In order to include orange –red fluorescence for pure white light generation we are doping LaPO4 with Eu3+. The crystalline planes are identified from the XRD pattern show that the particles have monoclinic structure with pure LaPO4. The addition of sodium ions to the LaPO4: Eu3+ sample it is found that the luminescence property gets increased. It is also found that reversal of the emission spectrum intensity takes place for the sodium doped sample which indicates that Eu3+ ions are located in a highly symmetric environment.
