“…The Y modes are located at around 180 cm −1 . 66 It is obvious that narrow peaks appear in Raman spectra of the crystal lattice with progressive Nb 5+ doping, which is in agreement with the PL studies where the higher PL intensity is observed for Nb 5+ -doped samples, as shown in Figure 9. 64,65 In addition, similar results could also be obtained in the YTiTaO 6 : 0.03Er 3+ , mNb 5+ system.…”

“…26 For wavenumbers between 200 and 400 cm À1 , the bands are due to the symmetric bending vibrations of O-Ti(Nb)-O, corresponding to n 3 F 1u , n 5 F 2g , and n 6 F 2u modes. 27 The last Raman band located at 155.43 cm À1 would be the euxenite-type lattice vibration, mainly associated with the RE ions. 24 Furthermore, the statistics conrm that the highest phonon energy of YTiNbO 6 is about 860 cm À1 , which is relatively lower than some inorganic oxide compounds such as phosphate, silicate and aluminate, etc.…”

“…Jacob et al (2007) reported the photoluminescence and low frequency dielectric properties of LnTiTaO 6 (Ln= Ce, Pr, Sm) ceramics. Recently, Solomon et al (2010) and Dhwajam et al (2011) reported microwave dielectric and optical properties, respectively of PrTiTaO 6 -YTiNbO 6 ceramic composites. They found that ε r and τ f values decrease systematically with the weight percentage addition of YTiNbO 6 ceramics (Solomon 2010) as well as both ε r and loss factor values decrease with radio frequencies whereas conductance values increase.…”
