Carbon dot hybrids with oligomeric silsesquioxane: solid-state luminophores with high photoluminescence quantum yield and applicability in white light emitting devices

摘要

We present a simple approach towards highly efficient solid-state luminophores with strong deep blue emission and a record high photoluminescence quantum yield of 60 by embedding water-soluble N, S-co-doped carbon dots into a polyhedral oligomeric silsesquioxane (POSS) matrix.
