Figure 3From: The modulation on luminescence of Er3+-doped silicon-rich oxide films by the structure evolution of silicon nanoclustersITPL intensity and energy transfer rate. ITPL intensity of Si NCs in the SRO and SROEr films (left coordinate) and energy transfer rate between Si NCs and Er3+ (right coordinate) as a function of Si excesses. The energy transfer rate increases with the Si excess.Back to article page
