The development of photosensitive glass (PG) has a remarkable history since its first commercial discovery in the 1940s. The manufacturing of PG is one of the most widely reported methods for special glass manufacturing. PGs are capable of forming permanent photographic images when subjected to light, providing security, high quality and productivity. The first U. S. patent about photosensitive glass was filed on December 8 th , 1943, and published July 18 th , 1950, by Stanley Donald Stookey. A historical perspective about photosensitive glass represents an important step for future applications. PG has been considered one of the most interesting research areas with potential industrial applications. A number of companies and institutions have explored the usefulness of such special glasses. In this paper, we investigated the number of published manuscripts and patents and determined the correlation of research activities to the production of new PG materials. The United States, Japan and China have been leaders in photosensitive glass development and have contributed to an impressive rise of activity in PG based on a number of new publications, author keywords, affiliations and primary characterization techniques. We verified that the number of published fundamental PG studies was greater from academic institutions than from industrial laboratories. According to the European Patent Office, more than 6,228 patents have been globally filed prior to 2013 with the terms "photosensitive" and "glass" within the title or abstract. These numbers have continued to grow along with worldwide PG-related sales. Based on the Scopus database, for the same period, 1,301 PG documents (primarily manuscripts) were published with the same terms in the title, abstract or keyword list. Statistically, there have been fewer worldwide publications of manuscripts than patents.

In this short statistical report, we compile and analyze statistics on past and current scientific and technological research on photosensitive glass (PG) as well as glass-ceramics (GC). Their developments have traced remarkable histories since their first commercial discoveries in the 1940s and 1950s, both the work of Don Stookey. These products and processes have transformed modern life and are two of the most widely reported methods for special glass manufacturing. They provide security, are of high quality mass production. The U.S., Japan and China have been leaders in PG glass development, the second place going to China in terms of GC research communities. We have observed very significant progress in recent decades with an exponential growth in the number of scientific publications and patents for PGs and GCs due to new publications, author keywords, affiliations and primary characterization techniques. More than 6,497 patents were filed globally prior to 2015 with the terms "photosensitive and glass" and 9,738 with the terms "glass and ceramics" within the title or abstract according to the European Patent Office. These numbers have continued to grow along with worldwide PG and GC-related sales. Based on the Scopus database, for the same period 1,405 PG documents and 30,819 GC-related (primarily manuscripts) were published with the same terms in the title, abstract or keywords list. From this statistical analysis, both PG and GC will continue to be fascinating materials for further research, development and uses in the near future.

Why took it nearly four decades, from the first evidence of artificial creation of bremsstrahlung, noted indirectly in literature in 1857 by Julius Pluecker, Professor of mathematics and physics in Bonn, Germany, to Professor Conrad Wilhelm Roentgen's breaking discovery and announcement of X-rays in 1895? Following introductory remarks on the difficulties adjusting the parameters required to generate X-rays and the way medical X-rays occupied clinical routine after Roentgen's revolutionary discovery, and answering the question at the beginning, this paper will discuss in depth the paths taken for improvement up to the present, and some of the culs-de-sac.the University of Pennsylvania, USA, in 1890, but were unable to elucidate them, see [50]. A single year after Roentgen sparking it, scientific, medical, and industrial development had exploded. Enabling technologies and physics in the 19th centuryThe history of medical and industrial X-rays and the evolution of the technology of its sources has fascinated now for about 125 years, see e.g. [2,[5][6][7][8][9][10]12,26,29,30,41,43,48]. Although alternative sources exist and despite of their deficiencies, see [6], vacuum electronics in the form of sealed-off X-ray tubes will remain the affordable sources of medical diagnostic X-rays also in the future, see [3,5]. This paper will track the various branches of the development of the technology, and briefly honor a few of those many scientists, developers, craftsmen, business leaders, and artisans, who have pushed innovation.Repeating Pluecker's, Hittorf's and later Lenard's experiments on cathode rays, Roentgen recognized X-rays on Friday, November 8th, 1895 in the Physical Institute of the University of Würzburg, Germany, see Fig. 1. Pluecker had begun reporting his findings in 1857, see footnote 1and [45], pg. 89. The British Professor of Physics at the University of Cambridge, UK Joseph John Thomson qualified cathode rays in 1896 as magnetically deflectable beams of "electrons". As Roentgen discovered in 1895, X-rays were something different. Hard scattering of electrons impacting on the atomic nuclei of, first, glass targets turned out essential to generate those highly energetic X-ray photons which are capable of transitioning portions of a human body
