Figure 2From: The modulation on luminescence of Er3+-doped silicon-rich oxide films by the structure evolution of silicon nanoclustersRoom-temperature PL spectra of Si NCs in the SRO and SROEr films. The Si excesses in SRO and SROEr films are (a) 11%, (b) 36%, (c) 58%, and (d) 88%, respectively. The Si NCs with separated microstructures and smaller sizes might be preferable to their luminescence performance.Back to article page
