Title: Effects of silicon nanostructure evolution on Er{sup 3+} luminescence in silicon-rich silicon oxide/Er-doped silica multilayers

Abstract

The effect of silicon nanostructure evolution on Er{sup 3+} luminescence is investigated by using multilayers of 2.5 nm thin SiO{sub x} (x<2) and 10 nm thin Er-doped silica (SiO{sub 2}:Er). By separating excess Si and Er atoms into separate, nanometer-thin layers, the effect of silicon nanostructure evolution on np-Si sensitized Er{sup 3+} luminescence could be investigated while keeping the microscopic Er{sup 3+} environment the same. The authors find that while the presence of np-Si is necessary for efficient sensitization, the overall quality of np-Si layer has little effect on the Er{sup 3+} luminescence. On the other hand, intrusion of np-Si into Er-doped silica layers leads to deactivation of np-Si/Er{sup 3+} interaction, suggesting that there is a limit to excess Si and Er contents that can be used.
