Abstract :
Increased percent molar ratio of zirconia (ZrO2) in Er3+-doped SiO2-ZrO2 glass-ceramic waveguide exhibits higher photoluminescence intensity. Zirconia helps to disperse Er3+ ions homogeneously within the glass ceramic matrix and reduced the formation of ion clustering. This effect results in reduced the number of cluster and promotes intense and stable photoluminescence. SiO2-ZrO2 planar waveguide thin films doped with 0.58 mol% of Er3+ were prepared via sol-gel technique.
