... ions. The present work aims to understand whether the SnO 2 nanocrystals can sensitize the Sm 3+ emission in the silica matrix. The one-step synthesis of the silica xerogels containing SnO 2 nanocrystals ... to the energy gap of the SnO 2 nanocrystals, while no emission of Sm 3+ ions can be observed for the samples containing Sm 3+ ions. The enhanceme...
