Figure 4From: The modulation on luminescence of Er3+-doped silicon-rich oxide films by the structure evolution of silicon nanoclustersRoom-temperature PL spectra and decay curves of Er3+ion. (a) Room-temperature PL spectra of Er3+ ion in the SROEr films. (b) Decay curves of PL signal recorded at 1,540 nm for Er3+ in SROEr films with Si excesses of 11% and 88%. Optimized Si NCs with separated microstructures are requested to obtain efficient Er3+ luminescence.Back to article page
