“…Transmission levels of ~83% ( t = 1.5 mm; λ = 700 nm) were exhibited by spinel PECSed at 1200°C for 15 min at 400 MPa . The low sintering temperature—at which carbon does not diffuse into the specimens—made possible pressing in the absence of LiF . Under similar sintering conditions and using LiF doping, Nd:YAG with a T = 80% at λ = 550 nm ( t = 2 mm) coupled with

Fifty years have elapsed from the moment the first light transmitting ceramic‐based commercial item—a sodium vapor‐based street lamp component—reached the market. This paper intends to be a brief chronicle (albeit not a chronology) of this first half century of translucent and transparent ceramic history. The main ceramic materials now available in a transparent state are presented and their main applications are described. Applications range from aerospace and relativistic optics to medical care, supermarket shopping, and modern warfare. Light transmitting ceramics usable as laser gain‐media, armor windows, IR domes, phosphors, scintillators, and electro‐optical components have been developed. The principal achievements this research produced are discussed. Processing strategies for full densification have been devised and quantitative relationships were established between different microstructural features such as amount and size distribution of porosity or level of birefringence, and the level of electromagnetic radiation attenuation they cause. Future prospects list ends the paper.

Doped transparent ceramics have potential for a wide range of optical applications derived from their easily controllable fluorescence properties. The aim of this contribution is to present and discuss an effective fabrication method for doped transparent yttrium aluminum garnet ceramics. The powder synthesis route was adapted from common co‐precipitation methods and the powder densification was performed by spark plasma sintering. Parameters of the fabrication process were optimized for different lanthanide dopants in order to obtain highly transparent single‐ and multi‐doped ceramics. The photoluminescence properties of the samples were measured and discussed. The use of lithium fluoride as a sintering additive was confirmed to be favorable and post‐sintering heat treatments were shown to be necessary for certain dopants. Finally, the photoluminescence lifetime of dopants in a multi‐doped sample were measured and the energy transfer efficiency between dopants was determined.
