Book Description
This handbook provides comprehensive treatment of the current state of glass science from the leading experts in the field. Opening with an enlightening contribution on the history of glass, the volume is then divided into eight parts. The first part covers fundamental properties, from the current understanding of the thermodynamics of the amorphous state, kinetics, and linear and nonlinear optical properties through colors, photosensitivity, and chemical durability. The second part provides dedicated chapters on each individual glass type, covering traditional systems like silicates and other oxide systems, as well as novel hybrid amorphous materials and spin glasses. The third part features detailed descriptions of modern characterization techniques for understanding this complex state of matter. The fourth part covers modeling, from first-principles calculations through molecular dynamics simulations, and statistical modeling. The fifth part presents a range of laboratory and industrial glass processing methods. The remaining parts cover a wide and representative range of applications areas from optics and photonics through environment, energy, architecture, and sensing. Written by the leading international experts in the field, the Springer Handbook of Glass represents an invaluable resource for graduate students through academic and industry researchers working in photonics, optoelectronics, materials science, energy, architecture, and more.

Book Description
This monograph covers the latest developments in lanthanide doped glasses and phosphor materials. The book aims to explain the basic functioning mechanisms of phosphor materials, and the luminescence behaviour of glasses doped with certain lanthanide ions. It also describes how to plot colors in a CIE chromaticity diagram. The book will be of use for senior researchers, materials scientists, chemists, physicists, engineers, as well as research students to gain knowledge on current developments of these materials.

Book Description
"The main objective of this research was to evaluate the properties and structures of glasses from the stannous (SnO) phosphate system for possible use in low temperature optical applications. Glasses in the binary xSnO-(100-x)P2O5 system (50[less than or equal to]x[less than or equal to]70) were prepared and their thermal and optical properties were evaluated. Differences in glass transition temperatures (T[subscript g]) measured here and reported in the literature were explained by differences in the residual water content in the glasses, as determined by infrared spectroscopy. In general, increasing the SnO content of the binary glasses increased the refractive index and the glass transition temperature, and reduced the residual water content, producing glasses that are more chemically stable. Raman spectroscopy showed that the chain-length of the average phosphate anion decreased with increasing SnO content. The addition of B2O3 to a Sn(II)-pyrophosphate base glass (x= 67) improves the aqueous dissolution rate by an order of magnitude. The impact of these compositional changes on the optical and thermal properties depends on how the borate is added. Raman and nuclear magnetic resonance spectroscopies reveal that boron is initially incorporated into the glass network in tetrahedral sites and the pyrophosphate anions are converted to orthophosphate anions. The effects of the addition of Ga2O3 and Sb2O3 on the properties of the tin phosphate glasses were also determined. In general, the addition of these modifying oxides increase the glass transition temperature from around 250°C to 350°C, and the refractive index (nD) was in the range 1.75-1.85, depending on glass composition. The chemical durability of these modified glasses was similar to those modified by B2O3-additions. Raman spectroscopy revealed the formation of isolated orthophosphate anions in the formation of Ga (Sb)-O-P glass networks"--Abstract, leaf iv.
