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 process, followed by poling through solvent evaporation along a thermal gradient, enabling the variation of the guests and hosts in order to tune the properties of the materials. The new method provides a versatile alternative to the thermal gradient zone melting technique.
