摘要
摘要-通过布里奇曼技术，在真空中使用 CF4 氟化气氛生长出了 Ba1 - x - yYbxRyF2 + x + y (R = Tm, Ho) 固溶体的单晶。我们测量了它们在 50-300 K 范围内的热导率以及从可见光到红外光谱区域的折射率。随着镱含量从 2 摩尔%增加到 14 摩尔%，R = Tm 和 Ho 固溶体的室温热导率分别从 3.39 W/(m K) 和 3.11 W/(m K) 下降到 1.18 W/(m K)。提高固溶体中钬和铥的含量会导致其折射率逐渐增加，并随着波长的增加而逐渐减小。
Thermophysical Characteristics of Single Crystals of Ba1 – x – yYbxRyF2 + x + y (R = Tm, Ho) Solid Solutions
Single crystals of Ba1 –x–yYbxRyF2 +x+y (R = Tm, Ho) solid solutions have been grown by the Bridgman technique in vacuum using a CF4 fluorination atmosphere. We have measured their thermal conductivity in the range 50–300 K and their refractive index from the visible to IR spectral region. As the ytterbium content increases from 2 to 14 mol %, the room-temperature thermal conductivity of the solid solutions with R = Tm and Ho decreases from 3.39 to 1.18 and from 3.11 to 1.18 W/(m K), respectively. Raising the holmium and thulium content of the solid solutions leads to a gradual increase in their refractive index, and it gradually decreases with increasing wavelength.
期刊介绍：
Inorganic Materials is a journal that publishes reviews and original articles devoted to chemistry, physics, and applications of various inorganic materials including high-purity substances and materials. The journal discusses phase equilibria, including P–T–X diagrams, and the fundamentals of inorganic materials science, which determines preparatory conditions for compounds of various compositions with specified deviations from stoichiometry. Inorganic Materials is a multidisciplinary journal covering all classes of inorganic materials. The journal welcomes manuscripts from all countries in the English or Russian language.
