Effect of Neodymium(III) Dopants on the Fluorescence Intensity of Bismuth(III) Phosphomolybdate

摘要

A solid-phase method is proposed for the preparation of K2Bi(PO4)(MnO4) with mean grain diameter 100 nm doped with Nd3+ ions in the concentration range from 1.0 to 10 mole %. The activator replaces a Bi(III) ion in the crystal lattice. The position of the emission bands of the resultant luminophores in the range 800-1150 nm is independent of the activator content, while the luminescence intensity is greatest for 5 mole % dopant.
