Abstract
The present invention relates to a solid-state blended polymer system that has the property of tunable lasing wavelength through adjusting the blending ratio. It can be used for health monitoring, environmental monitoring sensor and tissue imaging. Current materials do not have the broad tunable range; from blue to infra-red across the optical range. By using the same two polymers, it is possible to produce laser emitting blue to red colour. It simplifies the design, eases multi-wavelength laser sensor system integration and therefore, making the production cost-effective.
