“…All samples had a peak with a maximum intensity at ∼370 nm, attributed to valence band transitions within TiO 6 clusters. 66,67 In the emission spectra, the shoulder at 375 nm was explained by shallow defects near the conductance band. 67 It has been reported that TiO 6 clusters are responsible for photoluminescence in CCTO, whereas formation of TiO 5 clusters leads to photoluminescence quenching.…”

“…66,67 In the emission spectra, the shoulder at 375 nm was explained by shallow defects near the conductance band. 67 It has been reported that TiO 6 clusters are responsible for photoluminescence in CCTO, whereas formation of TiO 5 clusters leads to photoluminescence quenching. 68 The change in the balance between TiO 6 and TiO 5 might explain the observed photoluminescence quenching.…”
