Abstract
The present invention relates to a method for preparing photoluminescent silicon nanoparticles having uniformly hydrogen-terminated surfaces that are essentially free of residual oxygen. The present invention also relates to a method of preparing a blue-emitting photoluminescent silicon nanoparticle. The present invention further relates to a composition that includes a photoluminescent silicon nanoparticle having a surface that is uniformly hydrogen-terminated and essentially free of residual oxygen. The present invention also relates to a composition including a photoluminescent silicon nanoparticle having a surface that is uniformly coated with an organic layer and essentially free of residual oxygen. The present invention additionally relates to a composition including a photoluminescent silicon nanoparticle stably dispersed in an organic solvent and having a surface that is uniformly coated with an organic layer and essentially free of residual oxygen.
