Stimulated emission in organic films for longitudinal pulsed pumping

In this paper the generation of Rhodamine 800 (Rh 800) in ethanol and also mixtures of Pirrometen 597 and Rh 800 in transversal pumping and longitudinal types is investigated. TGF PMMA, Rh 800 solvents with copolymer PMMA IBMA films generation characteristics are obtained. Research was conducted at exaltation by the pulse laser wavelength of excitement is 532 nm, duration of an impulse is 10 ns, pumping power density is 13 MW/cm2). Films doped with the dye were created by a watering method (concentration of days = 5 × 10 - 4 moll/l). Thickness of films was measured using the optical profilometer KLA – Tencor MicroXam 100 and was obtained 5.8 microns

Conductive inks for inkjet printing based on composition of nanoparticles and organic silver salt

In this article, conductive inks for inkjet printing with high content of silver nanoparticles with the addition of organic silver salt and polymer additives are developed and investigated. Silver nanoparticles are shown to be stably dispersed in a solvent and the presence of a silver salt and a polymeric surfactant ensures the viscosity necessary for printing. A print of test images is performed using a laboratory inkjet printer equipped with an industrial small-droplet printhead followed by annealing of printed patterns at 150–250°C, and their structural and electrical properties are investigated. Simultaneous presence of polymer additives and silver salt is found to influence the structure of the forming conductive layer and the conducting properties
