A library of different crystalline sol-gel thin films with a composition of BaxTiyOz (where x = 1,2; y = 1,2,9 and z = 3, 7, 20) has been generated using variable multi-step laser and thermal annealing. Point by point X-ray diffraction characterization revealed the presence of high dielectric (BaTiO3) and low dielectric (Ba2Ti2O7 and Ba2Ti9O20) phases. Appropriate laser and thermal annealing controlled crystallinity, phase content, morphology and dielectric property of libraries. We have extended the process to BaTiO3 based thick-films and investigated the surface morphology of laser-annealed films.
