Spectroscopic properties in transparent

Major parf of analytical chemisfry is relafed to different spectroscopic techniques. In optical spectroscopy, ILs are already used as solvents for wide range of solutes to study their properties and behavior in conditions not available with organic solvents. ILs have their limits regarding the transparency, but knowing that many other limits are shifted far away. The use of ILs as solvents does not preclude the application of NMR techniques. After careful parameter adjustment, virtually all standard and advanced NMR techniques can be applied. The same can be said about mass spectrometry, which has a great potential to get a key method in almost all fields of IL research, including analytical applications with IL as necessary component to get good result.

Spectroscopic properties. The techniques of optical spectroscopy (ultraviolet, visible, and infrared spectrophotometry) are often used to examine the reactants or products of an electrode reaction. Obviously the solvent (and supporting electrolyte) must be transparent at the wavelength region of interest all of the commonly used dipolar aprotic solvents are transparent in the visible region. However, those solvents that contain aromatic or conjugated unsatu-... 

In this paper, Nd -doped yttrium lanthanum oxide transparent ceramics Nd (Yi-xLax)203 (x=0 0.1) were prepared. The spectroscopic properties of Nd (Y].xLax)203 transparent ceramic at room temperature were investigated.

The host materials that are utilized in laser systems must exhibit adequate transparency, mechanical strength, and thermal properties. In addition, the material must be able to sustain a precise optical polish, and be cast or grown adequately within reasonable economic and time constraints. The host must afford the impurity ions the type of spectroscopic properties that are appropriate for good laser performance. As a result of the numerous requirements, not many materials turn out to be useful in practical circumstances. Below, the nature of glasses and crystals is discussed, and the important physical properties are briefly outlined.
