Summary: YAG:Sm3+ transparent ceramics with 3-15 at.% Sm3+ doping were prepared by solid-state reactive sintering. The effect of samarium ions concentration on the microstructure and optical properties of the ceramics was investigated. It was found that the solubility limit of samarium ions in the garnet matrix was within the range of 9-11 at.%. The absorption coefficients corresponding to Sm3+ ions transitions increased linearly with increasing Sm3+ doping, and the intensities of the satellites and the broadening of the main spectral lines also increased with the concentration of Sm3+ ions. Highly-doped YAG:Sm3+ ceramics with 9 at.% Sm3+ ions showed low optical losses at 808 nm and a high absorption coefficient at 1064 nm, making them suitable for suppressing parasitic oscillations in YAG:Nd3+ lasers at 1064 nm.

Summary: In this work, a simple and efficient route for the coloration erasure and significant photoluminescence enhancement of lanthanide-doped transparent ceramics was developed. The full-band high transparency and efficient luminescence of YZO:Tb and YZO:Pr ceramics were achieved through air annealing plus vacuum re-annealing processes. The proposed defect clusters [Ln(Y)(4+)-O2--Ln(Y)(4+)] and [Ln(Y)(4+)-e'] provide insights into the relevant reaction mechanisms. The vacuum re-annealing strategy opens up a path towards controllably tailoring the optical properties of lanthanide-doped highly transparent ceramics.

Summary: The influence of annealing temperature in the range of 600-1200 degrees C on the mesostructure and properties of Y2O3:Yb3+ green bodies was investigated. It was found that annealing at the maximum possible temperatures without approaching particle centers is necessary for sintering. Green bodies annealed at 800 degrees C showed optimal mesostructure, resulting in the highest densification efficiency during subsequent vacuum sintering.

Summary: This study presents highly transparent Y2O3 ceramics fabricated at 1500 degrees C without HIP treatment, achieving in-line transmittance levels of 77% and 84% at wavelengths of 400 and 1100 nm. The influence of ball size during grinding on the optical properties of the samples was demonstrated for the first time. Results showed that using 2 mm balls led to the best combination of fine-grained structure and pore-free microstructure with optimal in-line transmittance for Y2O3 ceramics.
