The modulation of luminescence emission through external fields and stimuli has a significant application potential for light sources with variable colour and intensity as well as optical memories, switches and sensors. The main goal of the project is the fabrication of ferroelectric materials whose photoluminescence emission can be modulated in intensity, colour, etc. by the application of external physical stimuli, such as an electric field or a temperature variation. Moreover, the project aims at clarifying the fundamental mechanism behind the modulation process.
The materials will be developed both in bulk form (dense ceramics) and as thin films and, in the final part of project, we intend to assemble a simple thin film device to demonstrate the validity of the proposed idea.
The project is led by ICMATE-CNR and involves the institute SPIN-CNR
