Nanocomposites dendritic polyamidoamine-based chitosan hyperbranched polymer embedded in silica – phosphate for waveguide applications

Silica phosphate/chitosan-based dendritic hyperbranched polymer doped with Er3+ ions nanocomposite (i.e. SiPhDEr3+) was prepared by a sol-gel technique in monolith and thin film forms for planar wa...
