Pure and chromium(III) doped nanosized Al 2 (WO 4 ) 3 was prepared by co-precipitation method. X-ray, transmission electron microscopy, vibrational, absorption and luminescence studies of the obtained nanoparticles are reported. The particle size of the obtained samples ranged from about 20nm to a few hundreds of nm. Raman and IR studies showed that vibrational properties have...
Single crystals of the recently synthesized double tungstate NaAl(WO 4 ) 2 -doped with Cr 3+ were grown with the use of the top seeded solution growth technique by slow cooling of nonstoichiometric solutions. Measurements of the optical characteristics of samples with chromium concentrations in the range 1.4x10 19 -1.3x10 20 atoms/cm 3 ...
