| Abstract: | MBPO5: RE2+ (M = Ca, Sr, Ba; RE= Eu, Yb ) were synthesized with RE2O3,H3BO3, (NH4)2HPO4 and MCO3 as the starting materials in air, instead of preparing them inH2/N2 atmosphere. The peaks in their excitation and emission fluorescence spectra as well ashalf-widths of emission were measured. The results show that it is possible to preparedivalent Eu and Yb ions activated phosphors in air, if the crystal structure of the matrix enablesthese divalent ions to be stable in the light of its geometric factors and if the matrix itselfenables reducing trivalent Eu and Yb to be divalent. |
