The study of amino acid based nonlinear optical (NLO) materials with optimum physical properties is an important area due to their practical applications such as optical communication, optical computing, optical information processing, optical disk data storage, laser fusion reactions, laser remote sensing, colour display, medical diagnostics, etc. Also, microelectronic industries require cryst...

The cluster representation matrices have already been successfully used to enumerate close-packed vacancy clusters in all single-lattice crystals [I, 2]. Point defect clusters in double-lattice crystals may have identical geometry but are distinct due to unique atomic postions enclosing them. The method of representation matrices is extended to make it applicable to represent and enumerate ...

background: similar to the thermoluminescence (tl) spectra, the optical parameters variations can also be used in tl crystals for dosimetry purposes. these optical parameters can include absorption, transmission and reflection coefficients. materials and methods: single crystals of kbr and kcl which have been used in this research were grown from laboratory grade extra pure precursor powders. c...

In this study, the scintillation and optical properties of pure and silver doped potassium chloride (KCl:Ag) single crystals were reported. Pure and doped KCl bulk single crystals with a good optical quality and free from cracks were grown from the melt using Czochralski technique. Different analysis methods were used to study the optical and scintillation properties of the grown crystals. The ...

the reaction of [pphj, nos,] with cucl and kscn (1 :3:3) in acetone produces the yell-ow crystals of [pph,], [wos,(cuncs),]. the crystals are triclinic, space group p1(2), z=2, a=12.4823(7), b=12.9224(7), c=18.6395(10)?, ?=83.907(5), ?= 73.152(4), y= 65.194(4)'. the crystal structure was determined by single crystal xray diffraction methods (mo-k ?) and refined by least-squares calculation...

Abstract: fabricated. Modifications carried out in different parts of the old system in order to control mostof the growth parameters with more accuracy. The fabricated system was used to grow sapphiresingle crystals with almost 10 mm in diameter and 50 mm in length. The crystallinity andstructure of the grown crystals were characterized by computer aided single crystal X-raydiffraction techniq...
