Abstract

The drying conditions (in vacuum or in the air) of nanoparticles consisting of Yb:Yb₂O₃ + 5 mole% ZrO₂ obtained by sedimentation in ethanol have been found to affect the optical quality of the resultant ceramic samples. The studies were carried out using absorption spectroscopy in both the 200–1100 nm and near-infrared regions as well as Raman scattering. Regardless of the drying process for these nanopowders, carbonate species as well as fragments of ethanol and water are formed in the resultant ceramics, leading to complex crystalline defects containing divalent ytterbium ions. These defects lead to a loss of transparency of the ceramics and photoluminescence of trivalent ytterbium excited by laser radiation with wavelength 785 nm. The most significant negative effect of these defects was observed in the ceramics made of nanopowders dried in vacuum.

Yb:Y2O3 + 5摩尔% ZrO2纳米粉体在乙醇中沉淀对其合成陶瓷光学质量的影响

由Yb:Yb2O3 + 5mol % ZrO2组成的纳米颗粒在乙醇中沉淀得到的干燥条件（真空或空气中）影响了所得陶瓷样品的光学质量。利用200 - 1100nm和近红外吸收光谱以及拉曼散射进行了研究。不管这些纳米粉末的干燥过程如何，碳酸盐物质以及乙醇和水的碎片都会在合成的陶瓷中形成，导致含有二价镱离子的复杂晶体缺陷。这些缺陷导致了三价镱在波长为785 nm的激光激发下的光致发光。在真空干燥的纳米粉体陶瓷中观察到这些缺陷最显著的负面影响。
