Structure, mechanical, optical, and imaging contrast features of Yb , Dy , Tb , Gd , Eu , and Nd substituted Y O -Ln O solid solution.

Bulk ceramic that possess the combined features of structural stability at elevated temperatures, appropriate mechanical stability, luminescence features, magnetic resonance (MR) and computed tomography (CT) imaging capacity in a single platform is considered an exciting prospect in biomedical applications. In this study, six different lanthanides (Ln :Yb , Dy , Tb , Gd , Eu , and Nd ) were combined together to yield a Y O :Ln O solid solution and subsequently tested for the proposed application. Three different Y O :Ln O solid solutions were formed by varying the concentrations of Ln precursors.

Bulk Yttria as a Host for Lanthanides in Biomedical Applications: Influence of Concentration Gradients on Structural, Mechanical, Optical, and Imaging Behavior.

The biomedical application of yttria (YO) as a bulk material to host a series of rare earth elements (RE) has been explored in the current investigation. Dy, Gd, Tb, Yb, Eu, and Nd were chosen for this purpose, and their corresponding concentrations in YO have been varied to obtain five different combinations. The results ascertain the potential of YO to host different RE to retain a discrete cubic yttria (-YO) devoid of significant structural distortion until 1400 °C.

Unveiling the Effects of Rare-Earth Substitutions on the Structure, Mechanical, Optical, and Imaging Features of ZrO for Biomedical Applications.

The impact of selective rare-earth (RE) additions in ZrO-based ceramics on the resultant crystal structure, mechanical, morphological, optical, magnetic, and imaging contrast features for potential applications in biomedicine is explored. Six different RE, namely, Yb, Dy, Tb, Gd, Eu, and Nd alongside their variations in the dopant concentrations were selected to accomplish a wide range of combinations. The experimental observations affirmed the roles of size and dopant concentration in determining the crystalline phase behavior of ZrO.
