摘要：

Transparent bulk xKTP-(1 - x)SiO2 nanocomposites, containing nanocrystalline KTiOPO4 (KTP) dispersed in silica glass matrix, were fabricated by the sol-gel method, The transmission properties of KTP/SiO2 have been measured between 2500 and 300 nm and show transmission of 30% at 0.532 mu m and 60% at 1.064 mu m. The nanocomposite glasses exhibit an UV cut-off at 350 nm. The second harmonic generation (SHG) was observed from xKTP-(1 - x)SiO2 nanocomposites or glass-ceramics. The intensity of the SHG signal in the nanocomposites increases as a function of KTP concentration. (C) 2000 Elsevier Science B.V. All rights reserved.
