Abstract

The Dy:PBiNaGd glasses were made from chemical compounds with a composition (70-x)P₂O₅-10Bi₂O₃-10Na₂O-10Gd₂O₃ which were doped by active xDy₂O₃ ion (where x = 0; 0.05; 0.1; 0.5; 1.0; 3.0 (mol%). All of proposed compositions are in the powder form with a mass of 20 gram of mixture in an alumina crucible and prepared by the melt-quenching method. The glasses those have been obtained with a size (3 × 10 × 10) mm³ and smoothed to get a flat surface and high transparency. The physical properties including of density, molar volume, refractive index, ion concentration, molar refractivity, and susceptibility of the glasses medium have been obtained and analyzed. This amorphous nature is confirmed by x-ray diffraction instrument (XRD). Based on the XRD ovservation found that the Dy:PBiNaGd glasses are amorphous. Measurement of FTIR spectra for Dy:PBiNaGd glass shows that the asymmetry strain in the P-O-P (POP) bond appear at an area of 861 cm⁻¹ absorptions.

摘要

Dy：PBiNaGd玻璃由化学成分为（70-x）P ₂ O ₅ -10Bi ₂ O ₃ -10Na ₂ O-10Gd ₂ O ₃的化合物制成，并掺杂有活性xDy ₂ O ₃离子（其中x  = 0; 0.05; 0.1; 0.5; 1.0; 3.0（mol％）。所有提出的组合物均为粉末形式，其质量为20克在氧化铝坩埚中的混合物，并通过熔融淬火法制备。尺寸为（3×10×10）mm ³并进行平滑处理以获得平坦的表面和高透明度。已获得并分析了包括玻璃介质的密度，摩尔体积，折射率，离子浓度，摩尔折射率和磁化率在内的物理性质。通过X射线衍射仪（XRD）证实了这种无定形性质。根据XRD观测，发现Dy：PBiNaGd玻璃是无定形的。Dy：PBiNaGd玻璃的FTIR光谱测量表明，POP（POP）键的不对称应变出现在861 cm ^-1吸收区域。
