Growth and optical properties of Tm:YAlO3 single crystals with different Tm concentrations

Structural Evolutions and Crystal Field Characterizations of Tm-Doped YAlO3: New Theoretical Insights

“…The bond lengths of the nearest interatomic distances of the Tm:YAP single crystal are in good agreement with the experiments reported by Matkovskii et al Moreover, the bond lengths of Tm–O and Y–O are also quantitatively similar to each other, indicating that no distinct structural distortion occurred between the pure and the Tm-doped YAP. This lack of distortion may be because Tm 3+ (0.87 Å) has a similar radius and electronic configuration as Y 3+ (0.88 Å) . The calculated and experimental measured lattice parameters for the pure YAP and the Tm-doped YAP crystals are summarized in Table S1. , …”

Anisotropy of thermal and spectral characteristics in Tm:YAP laser crystals

“…It is worth mentioning that the effective segregation coefficient of Tm 3+ in YAP crystal is about 0.88 [23]. From the equation above, σ abs at the peak wavelength was determined to be 8.64, 9.22 and 6.80 × 10 −21 cm 2 along crystallographic a-c-axes.…”

Effect of concentration on the spectral properties of Tm3+ ions in bismuth borate glasses

“…Recently, some researchers have investigated the relation between spectral properties of some rare earth ions and concentration. Lu et al [24] have investigated that the optimized Tm 3+ concentration doped in YAlO 3 single crystal is 4 at%. Balda et al [25] have found that the 3 H 4 → 3 F 4 emission intensity was decreasing in relation to the 3 F 4 → 3 H 6 emission as Tm 3+ concentration increases in TeO 2 -TiO 2 -Nb 2 O 5 glass, due to the presence of cross-relaxation processes and have revealed that the dipole-dipole quenching process in the framework of a diffusionlimited regime was responsible for the ion-ion interaction.…”
