Abstract

Abstract Exposure of solutions of Tb (N (SiMe 3) 2) 3 with SiCl (NEt 2) 3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb: SiN x phosphors that exhibit bright green luminescence under UV irradiation. MAS-NMR and combustion analysis reveal that the phosphors are silicon nitride materials analogous to those typically produced by sol–gel routes. Photoluminescence ...
