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.

“…Ln 3+ -doped Ba perovskite-type oxides such as BaTiO 3 :Sm 3+ and BaZrO 3 :Eu 3+ are typical examples where such a request is satisfied . Besides, Ba(Zr,Mg,Ta)O 3 :Nd 3+ is reported to show Nd 3+ luminescence from both A and B sites according to the chemical composition of the host lattices . Because the Ln 3+ luminescence from both A and B sites in one simple perovskite-type host lattice is rare, the location of the activators at the A or B sites has not drawn so much attention in such materials, as has the Ln 3+ luminescence.…”

Luminescence and Location of Gd³⁺ or Tb³⁺ Ions in Perovskite-Type LaScO₃

The luminescence properties of Gd or Tb ions at La and Sc sites were investigated in LaScO with a distorted perovskite-type structure (ABO). Although the luminescence of lanthanide ions located at B sites is not common and has not been examined in detail, Gd or Tb luminescence from B sites and A sites is clearly observed in Gd- or Tb-doped LaScO. The differences in the luminescence characteristics concern peak positions, peak shapes, and decay time, which are all influenced by the crystal field and the site symmetry. The UV luminescence of Gd at B sites shows a red shift compared to Gd at A sites, and the green luminescence of Tb at B sites contrasts with the blue-violet and green luminescence of Tb at A sites. The decay time of the luminescence from B sites is systematically longer than that from A sites in both the Gd and Tb cases.

“…Utilizing this feature, Ba(Sn,Zr,Mg,Ta)O 3 transparent ceramics was put into practical use as the world's first ceramics lens for digital still camera in 2004. Not only lens applications but other applications such as a laser and a fluorescent material would be available for the transparent ceramics [16]- [18]. As described in this paper, the crystal structure is preferred to be cubic for obtaining transparency in ceramics, while, recently, high transmittance was obtained even in a hexagonal structured material by reducing grain sizes to sub-micron order [19].…”

Transparent dielectric ceramics were developed originating from dielectric ceramics of which development was conducted by Dr. Wakino for microwave applications. A Ba(Mg,Ta)O 3 based transparent ceramics shows high transparency and various optical properties depending on the composition. Based on the knowledge obtained from the study of Ba(Mg,Ta)O 3 based transparent ceramics, we also developed other transparent ceramics such as LaAlO 3 -Sr(Al,Ta)O 3 solid solution. The Ba(Mg,Ta)O 3 based transparent ceramics was commercially utilized as high-refractive-index lens for slim digital camera applications, where the refractive indices reduced the focal length of optical lens modules.
