(MoO4)3 NASICON-like solid solutions, where R = Al or Sc and 0 ≤ x ≤ 0.5, were prepared; their crystal lattice parameters and thermal stabilities were determined. Silver-ion conductivity was
measured, and conductivity activation energy values were calculated for various temperature ranges. Above 400°C, Ag1 − x

(MoO4)3 phases have ionic conductivities comparable to the conductivities of sodium-ion and lithium-ion NASICON-like conductors.
The conductivity increases as the tervalent cation radius increases or the amount of mobile silver ions increases. 相似文献

Luminescent properties of anodic alumina fabricated in anodizing solutions containing oxalic, sulfuric, and phosphoric acids
in addition to those modified by thermal annealing are investigated. Comparison of the obtained data shows that F+-centers are responsible for the luminescence band at 390 nm. The intense photoluminescence band of porous anodic alumina
substrates at 450–500 nm is associated with oxalate anions.

The possibility of generation of a surface plasmon resonance by gold nanoparticles in a 3D network polymer matrix upon irradiation
of a liquid acrylic composition containing a dissolved Au3+ salt is demonstrated for the first time. UV-irradiation of the solution simultaneously causes gold photoreduction to Au0 and acrylate photopolymerization. The possibility of preparing transparent colorless films that, when heated or exposed to
light, give rise to a visible-spectrum absorption band belonging to a plasmon resonance of metal nanoparticles is demonstrated.
The intensity and position of the plasmon resonance band depend on the parameters of the 3D polymer network, chemical structure
of the oligomer, type of the support, and conditions of formation of Au0 particles. The formation of reduced gold nanoparticles responsible for the plasmon resonance band occurs more effectively
in low-density networks with a large interchain length and containing oligomer block capable of complexation with the metal.
The formation of nanoparticles is affected by the chlorine-containing products of the reduction of the gold salt. 相似文献

Methods for beam shaping with nonzero orbital angular momentum are studied using diffraction optical elements with the purpose of developing a source of single-photon states based on spontaneous parametric down-conversion of light in the LiNbO3 crystal in the cavity resonator. The probability of the coincidence of the number of photocounts in detecting signal and idle fields under pumping by a beam with the orbital angular momentum is simulated. 相似文献
