Abstract

We demonstrate the successful incorporation of luminescent Pr3+ ions into TiO2 split ring resonator-like micro-crystalline structures embedded in SrTiO3, which are obtained by derectional solidification of the SrTiO3-TiO2eutectic. Raman and fluorescence spectroscopy reveal that Pr3+ incorporates into both component phases, the spectra features of each compound being spatially separated. Confocal spectroscopy maps are found to correlated well to the composition and crystal orientation of the heterostructures. The results suport the feasibility of engineering trivalent rare-erth ion doped self-organized oxide-oxide eutectic structures as potential candidates for photo-electrochemical or photoactive devices based on novel TiO2 structures.
