C-dot sensitized Eu3+ luminescence from Eu3+-doped LaF3–C dot nanocomposites†
Abstract
Very strong Eu3+ luminescence is achieved via sensitization by carbon dots (C-dots) in Eu3+-doped LaF3–C-dot nanocomposites for the first time. This energy transfer via C-dots leads to the broadband excitation of Eu3+ ions which can have potential use in phosphor based LEDs.
