Structural and optical properties of Er3+-doped Y2Ti2O7 thin films by sol–gel method

Novel non-toxic and red luminescent sensor based on Eu3+:Y2Ti2O7/SiO2 nano-powder for latent fingerprint detection

“…A characteristic crystalline peaks for cubic lattice Y 2 Ti 2 O 7 at high annealing temperature (1000 o C) scattered from the amorphous silica (JCPDSNo.42-0413, a=10.095 Å) [17]. The crystalline peaks of Y 2 Ti 2 O 7 are quite large, indicating that a nano-phase is formed in agreement with TEM results reported in the following [18][19]. In addition, with the increase of annealing temperature, the diffraction profile peak of amorphous silica moves towards a small angle.…”

Effect of Li+ Ions Doping on Microstructure and Upconversion Emission of Y2Ti2O7:Er3+/Yb3+ Nanophosphors Synthesized Via a Sol–Gel Method

“…Yttrium titanate (Y 2 Ti 2 O 7 ), one of the classical pyrochlore compounds, is a potential and promising host material for efficient luminescence owing to relatively low phonon energy (smaller than 720 cm −1 ), high dielectric constant, and excellent chemical and thermal stability . In our previous work, bright visible UC emission could be clearly observed with naked eyes in Er 3+ /Yb 3+ codoped Y 2 Ti 2 O 7 nanophosphors under 980‐nm excitation at room temperature, and the Er 3+ and Yb 3+ ion doping concentrations were also optimized .…”

Structural, optical and mechanical properties of Y2Ti2O7 single crystal

“…The Y2Ti2O7 compounds are known to have high mechanical strength due to the short inter-atomic distances of Ti-O and Y-O bonds, in which Ti-O bond has higher covalent character [8]. Despite a considerable amount of literature is available on the structural, optical and electrochemical properties [2][3][4][5]9], the studies on mechanical properties of Y2Ti2O7 compounds are limited and still it is an active subject of theoretical and experimental research [8,[10][11][12].…”
