NOVEL COLORLESS COMPOSITE-MATERIALS FOR NONLINEAR OPTICS

Colorless SHG-active composite materials could have great potential in nonlinear optics applications, for example in optoelectronic devices. The composite materials are produced using a novel solution-based pro cess, followed by poling through solvent evaporation along a thermal g radient, enabling the variation of the guests and hosts in order to tu ne the properties of the materials. The new method provides a versatil e alternative to the thermal gradient zone melting technique.
