Preparation of nonlinear glass-SiO2 containing KTiOPO4 nanocrystal by sol-gel method

A nanocomposite glass containing nanocrystalline KTiOPO4 (KTP), were synthesized by sol-gel processes.After heat treatment at temperatures higher than 750°C, the K2O-TiO2-P2O5-SiO2 gel monoliths transformed into aKTPnanocrystals embedded in SiO2–based glass. The nanocomposite glass in the 20KTiOPO4 -80SiO2 systems werecharacterized and examined by X-ray diffraction ( XRD) anddifferential thermal analysis (DTA).
