ABSTRACT: The concept, as well as the methodology of using a
mineral-inspired approach in combination with solution parallel synthesis (SPS)
for exploration of new phosphors among Na/Sr(Ba)/Al-silicate and Zr(Ti)-silicate
minerals, is reported. By employing the proposed approach, we have discovered
new phosphors of NaAlSiO4:Eu2+ and BaZrSi3O9:Eu2+,
that emit green-yellow (553 nm) and blue-green (480 nm) light, respectively,
when excited by radiation of 290 to 420 nm.
