Nonoxide Sol-Gel Synthesis of Terbium-Doped Silicon Nitride Phosphors
Nonoxide Sol-Gel Synthesis of Terbium-Doped Silicon Nitride Phosphors
Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx 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 behavior is similar to that of Tb:SiNx or Tb:SiO2 films produced by ion implantation that show good electroluminescence activity.

Abstract
Exposure of solutions of Tb(N(SiMe3)2)3 with SiCl(NEt2)3 in tetrahydrofuran to dry ammonia results in polymeric xerogels. Heating these gels in ammonia leads to amorphous Tb:SiNx 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 behavior is similar to that of Tb:SiNx or Tb:SiO2 films produced by ion implantation that show good electroluminescence activity.
