ABSTRACT

Ytterbium doped TiO2 nano-particles were prepared via Sol-Gel Technique under varying conditions to investigate the effects of Ytterbium ion doping on the Titania optical properties in MID IR range. X-ray diffraction analyses show that prepared Yb3+ doped TiO2 samples have polycrystalline structure in Anatas phase. FTIR spectrums for pure and doped samples after annealing process show a single transmission peak at wave number around 1145 cm-1. Transmission rate of this peak depends on Yb3+ concentrations and its value rises from 1.82% (for pure TiO2) to 58.1% (for doped with 1.13 wt% Yb3+). Slightly peak shift occurs at a lower doping rate with no further response to higher concentration rate. FTIR spectra gives a good indication in direction of preparation of optical band-pass filter at a wavelength around 8.733 μm (~1145 cm-1).
