Taschenbuch. Etat : Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -For the formation of crystals, it is important to understand the theories of crystal growth. The gel method can be used at room temperature or at low temperature conveniently. For those substances having very slight solubility in water and the crystal of which cannot be satisfactorily grown from melt or vapor, it gives reasonable prospects of success. The low solubility and lower dissociation temperatures of the tartrate compounds impose several constraints in adopting solution technique. But the gel method stands out as an efficient technique for growth of tartrate crystals. Tartrate crystals grown by gel method have potential applications in piezoelectric devices, medical equipments, fiber optics, and NLO field. In present work, the good quality, uniformly well developed crystals are grown by gel method for different conditions under optimized preparative parameters, such as concentration of supernatant, pH of solution, density, aging of gel, temperature etc. The grown crystal are characterized by using Scanning electron microscope (SEM), X-ray diffraction (XRD),Thermal analysis, FT-IR, EDAX, Electrical conductivity and UV-VIS Spectroscopy. 160 pp. Englisch.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - Single crystals are the fundamental building blocks for modern technology. Growth of crystals by gel method is a promising technique for growing single crystals. Nonlinear optical materials (NLO) exhibiting second harmonic generation have been in great demand due to technological importance in the fields of optical communication. Existing organic NLO crystals have poor mechanical and thermal properties and are susceptible to damage during processing even though they have large NLO efficiency. Purely inorganic NLO materials have excellent mechanical and thermal properties. Very little information is available on the studies of various properties of iodate crystals and practically very few attempts have been made to study growth and characterization of iodate crystals. In view of the above, it is decided to grow and study Strontium iodate and Zinc iodate crystals which possess shorter cutoff wavelength, good optical quality, sufficient nonlinear coefficient, transparency in the UV region and excellent thermal stability. Studies on Growth and Thermal, Electrical and Optical properties of Strontium iodate and Zinc iodate have been carried out and results are described in this book.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - El método de gel es una técnica prometedora para el crecimiento de cristales individuales de sustancias poco solubles en agua y que se descomponen antes de su punto de fusión. En el método de gel, la velocidad de difusión de los reactivos podría controlarse, ya que los geles son redes de cavidades de varias decenas a varios miles de angstroms de diámetro, que se comunican a través de orificios ligeramente más pequeños. Los materiales ópticos no lineales (NLO) que presentan generación de segundo armónico han tenido una gran demanda debido a su importancia tecnológica en los campos de la comunicación óptica. La mayoría de los cristales orgánicos NLO suelen tener malas propiedades mecánicas y térmicas y son susceptibles de sufrir daños durante el procesamiento, aunque tienen una gran eficiencia NLO. Los materiales NLO puramente inorgánicos tienen excelentes propiedades mecánicas y térmicas. Por lo tanto, se decidió cultivar y estudiar cristales de yodato de cobalto y tartrato de cobalto mediante el método de gel, que poseen una longitud de onda de corte más corta, buena calidad óptica, suficiente coeficiente no lineal, transparencia en la región UV y excelente estabilidad térmica, y se caracterizan por el uso de XRD, FT-IR, TGA/DTA, EDAX, SEM, conductividad eléctrica, fotoluminiscencia y espectroscopia UV-VIS.…

Taschenbuch. Etat : Neu. nach der Bestellung gedruckt Neuware - Printed after ordering - La méthode des gels est une technique prometteuse pour la croissance de monocristaux de substances peu solubles dans l'eau et qui se décomposent avant leur point de fusion. Dans la méthode des gels, le taux de diffusion des réactifs peut être contrôlé, car les gels sont des réseaux de cavités de plusieurs dizaines à plusieurs milliers d'angströms de diamètre, communiquant par des orifices légèrement plus petits. Les matériaux optiques non linéaires (NLO) présentant une génération de seconde harmonique sont très demandés en raison de leur importance technologique dans les domaines de la communication optique. La plupart des cristaux NLO organiques ont généralement de mauvaises propriétés mécaniques et thermiques et sont susceptibles d'être endommagés lors du traitement, bien qu'ils aient une grande efficacité NLO. Les matériaux NLO purement inorganiques ont d'excellentes propriétés mécaniques et thermiques. Par conséquent, il a été décidé de faire croître et d'étudier des cristaux d'iodate de cobalt et de tartrate de cobalt par la méthode du gel, qui possèdent une longueur d'onde de coupure plus courte, une bonne qualité optique, un coefficient non linéaire suffisant, une transparence dans la région UV et une excellente stabilité thermique et sont caractérisés par l'utilisation de XRD, FT-IR, TGA/DTA, EDAX, SEM, conductivité électrique, photoluminescence et spectroscopie UV-VIS.…
