Luminescence of Pr 3+ and Nd 3+ Ions in Double Molybdates

The optical spectra of samples of double zirconium molybdates activated by rare-earth Pr3+ and Nd3+ ions are studied. The presence of bands corresponding to the 4f–4f transitions of Pr3+ and Nd3+ trivalent ions in the absorption, excitation, and luminescence spectra is shown. A strong dependence of the luminescence intensity of Pr3+ ions on temperature is revealed.
