Ultra-broad plasma resonance enhanced multicolor emissions in an assembled Ag/NaYF4:Yb,Er nano-film.
Here, we present the preparation of a Ag/NaYF(4):Yb,Er composite film via a simple assembly method and its considerably enhanced multicolor emissions owing to the strong coupling between the 980 nm excitation light and the ultra-broad surface plasma resonance (SPR) of silver.
