Abstract

Film fabrication of LiTaO₃ has been successfully prepared with 0%, 2%, 4%, and 6% Iron containing variations using the Chemical Solution Deposition (CSD) method. Each sample was characterized using FTIR and the wavenumber and transmittance values were obtained. This value was analyzed using the Kramers-Kronig (KK) method and obtained the Transverse Optic (TO) and Longitudinal Optic (LO) values. The results show that TO value is in wave numbers 462.25 cm^-1 – 556.00 cm^-1. While the value of LO is in the range of wave numbers 478.50 cm^-1 – 571,00 cm^-1. The results show an increase in both TO and LO values as the Iron Oxide percentage increases. Based on the analyses of TO, LO, ε₁ and ε₂, film fabrication of LiTaO₃ has the potential as light, pressure and temperature sensors.
