Special Issue Information

Dear Colleagues,

Transparent bulk ceramics constitute one of the latest developments in the general field of technical ceramics. The past 50 years have shown strong evolution and innovation in this research area.

Transparent ceramics combine the transparency abilities of classical windows, made from others materials (inorganic glasses, polymers, single-crystals), with the specific functional properties of polycristalline ceramics. This makes them attractive for applications in various domains. Most of manufactured transparent ceramics for industry are simple, bulk transparent parts, whereas some others are highly sophisticated, with complex shapes and/or architectures (composition gradient). Examples include optically-passive, such as transparent armor, infrared windows, optical lenses, artificial gems, and transparent parts for jewelry, or optically-active devices, such as scintillators, amplifiers, or Q-switch media for laser systems.

With their need for full densification, each step of the manufacturing process must be controlled perfectly. For this purpose, many advances were made in various scientific and technological fields, such as powder synthesis, shaping, and sintering. Non-exhaustively, the synthesis of nanoparticles using soft chemistry, green compact shaping, using either solid methods (Cold Isostatic Pressing) or liquid methods (casting of suspensions), and sintering using pressure-less or pressure-assisted techniques (Hot Pressing, Spark Plasma Sintering, Hot Isostatic Pressing, etc.) have been proven to be suitable for obtaining transparent ceramics. Whatever the manufacturing process, the global goals are to ensure a high purity with limited contamination, and to promote particle/grain and pore size homogeneity.

One of the most emblematic transparent ceramic material in the two past decades Yttrium-Aluminum Garnet (YAG)-based transparent ceramics, has revolutionized laser technology: it is now possible to manufacture large pieces of tens centimeters with high doping levels and complex architectures (pieces with composition gradient—also called composites); as opposed to single-crystal technology. Recently, powerful lasers, operating at up to 100 kW, have been demonstrated to be feasible. There are many other transparent ceramics and applications, indicating the great potential of this research area.

It is my pleasure to invite you to submit a manuscript for this Special Issue. Original research, in the form of full papers, short communications, and reviews, are all welcome.

Manuscripts can be submitted until the deadline. All papers will be peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Materials is an international peer-reviewed open access monthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Transparent MgAlON:Ce fluorescent ceramics with doping content of 0.005, 0.01, and 0.02 at % were fabricated by pressureless sintering. All the samples were dense and large in grain size. Under the excitation of 320 nm UV, the samples emitted blue lights centered around 410 nm. The 0.005 and 0.01 at % Ce3+ doped samples were single phase by XRD detection, and possessed good optical and mechanical properties, and luminous thermal stability. The fluorescence lifetime, the CL and PL spectra analysis, indicated that most of the luminous centers were segregated in GB, and there was still a small part of second phase existing in 0.01 at % Ce3+ doped sample, which revealed that spectroscopy methods possessed better sensitivity in smaller scale and lower concentration detection than XRD. As the doping content increasing to 0.02 at %, a mass of second phase arose, which resulted in the optical transparency, mechanical property, luminous thermal stability decline, and the PL spectra red shift by the formation of second phase. It revealed that the performances were fatally deteriorated by excess doping of Ce3+ ions. Full article
