“…This mismatch has an impact on lattice distortion of TiO 2 . 20,32,33 Therefore, substitution of Ti 4+ in its lattice site is less probable than interstitial incorporation or segregation of Ln 3+ ions at the grain boundaries. 20 The EDS elemental analysis results (Fig.…”

“…20,32,33 Therefore, substitution of Ti 4+ in its lattice site is less probable than interstitial incorporation or segregation of Ln 3+ ions at the grain boundaries. 20 The EDS elemental analysis results (Fig. 1), considering the semi-quantitative character of this technique, correlate well with the composition of the targets used for the sputtering.…”

“…Among them, the sol-gel method exhibits some advantages such as ease of synthesis, high homogeneity, and purity [26,27]. In our knowledge, the previous reports have mainly focused on the thin films of TiO 2 doped RE ions [17,[28][29][30] and there are a few of publications on TiO 2 :Er powders [30][31][32]. In addition, the studies of the effect of excitation wavelengths on optical properties and the dual-model up/down-conversion luminescence of TiO 2 :Er have not been reported in the literature.…”

“…Despite this, TiO2 has been widely employed as a photocatalyst for dye degradation due to its strong photocatalytic activity, nontoxicity, chemical stability, photostability, and economic viability [9,15]. The energy gap of TiO2 in anatase phase is equal to 3.2 eV, therefore it is photoactive in the UV region (λ< 388 nm) and its application is limited by a very poor response to visible light [16]. The UV band has accounted for 3-5% of total solar energy used.…”
