Synthesis, Structure and Luminescence Properties of Rare-Earth Double Phosphates

Abstract:

The main crystallization trends of rare-earth complex oxides from alkaline phosphate-molybdate (tungstate) melts have been studied in a light of structure - luminescence properties relationships. The regions of formation MI3RE(PO4)2, REPO4 and M^I₂RE(PO₄)(M^VIO₄) from self flux systems M^I–P–RE–O (M^I–alkaline metal; M^VI–Mo, W) have been defined. The influence of MI/MVI ratio in the initial melt has been shown to play the key role in solid phase formation and structural peculiarities of REO_x polyhedral condensation of compounds obtained.
