Resumen:
In this work were successfully synthesized bulk samples of Ca1-2xLnxNaxWO4 with x = 0 and 0.1 and Ln= Eu, Sm as crystalline white powders, and the structure of the schelite (CaWO4) was used as thereceiving matrix. For the synthesis a novel mechanical-thermal method of three steps was applied,which included activation, miniaturization by high-energy milling, and further calcination. Then, toobtain the nanoparticles (NP) a fine grinding was carried out. Unlike traditional synthetic routes, thismethodology does not use solvent and has a relatively low calcination temperature; so a ?green? methodto obtain optical materials was achieved.
