Second harmonic generation of template synthesized PbTiO3 nanostructures

The lead titanate (PbTiO 3 ) nanotubes were prepared with a chelate sol-gel of titanium isopropoxide (Ti(O i Pr) 4 ) and lead acetate (Pb(OAc) 2 -3H 2 O) by using AlO x template. Whatman® anodisc membranes (with a 200 nm pore size) served as the template. The template was dipped into the precursor, PbTiO 3 solution, allowed to air dry, and then calcined at 650 °C. Recently, we have characterized a signal of second harmonic generation (SHG); 532 nm on 1064 nm of Nd:YAG laser beam in the PbTiO 3 nanotubes with AlO x template.
