Two techniques often used in semiconductor industry, namely, low-pressure chemical vapour deposition (LPCVD) and plasma enhanced chemical vapour deposition (PECVD), were used to deposit silicon-rich oxide layers. Thermal treatments have been performe

By quantifying the amount of excited Er ions and considering the interaction distance between Si nanoclusters (Si-ncs) and the nearby Er ions, we were able to determine the maximum excitable Er concentration, when indirectly pumped through the Si-ncs
