Thermal Enhancing of Upconversion by Negative Lattice ...Herein, a novel strategy is established to enhance upconversion luminescence at elevated temperatures based on the use of negative thermal expansion host materials. Lanthanide‐doped orthorhombic Yb2W3O12 crystals are synthesized and characterized by .

Geophysical Journal International Princeton UniversityEffective orthorhombic anisotropic models 1655 2 DISPERSION RELATION Kinematic signatures of P waves in pseudoacoustic anisotropic orthorhombic media depend on only five anisotropic parameters and the vertical velocity as shown by Tsvankin (1997). Instead of rigorously using the notation suggested by Tsvankin (1997), we implement a

Magnetic order of the Pr sublattice in tetragonal and ...Abstract. 155 GdMöss studies of (Pr Gd )Ba 2 Cu 3 O 7δ in the tetragonal ( δ = ) and orthorhombic ( δ = ) phase reveal transitions to magnetic order at T N = K and K, respectively, of the Pr sublattice. The hyperfine interaction parameters of 155 Gd in the orthorhombic sample above T N compare well with those data obtained in orthorhombic GdBa 2 Cu 3 O 7δ ...
Optical and Piezoelectric Properties of Strained ...Abstract: We investigate optical and piezoelectric properties of the orthorhombic PdS 2 under symmetrical biaxial tensile strains with various magnitudes. The ab initio simulation results found that the peaks of the refractive index, extinction coefficient, absorption coefficient, and reflectivity of the orthorhombic PdS 2 redshift with the tensile strains.
