Fabrication and properties of tape casting transparent Ho:Y3Al5O12 ceramic

High-quality holmium-doped Y3Al5O12 (YAG) ceramic is fabricated in sequence by tape-casting and vacuum sintering. The average grain size of the Ho:YAG ceramic is around 20 μm with a fully dense microstructure. The inline transmittance of the sample is ~82% in visible and IR region. The fluorescence
