The aim of STABILIGHT is the design and demonstration of novel nano-photonic devices based on all inorganic nanostructured materials operating at low DC voltage with enhanced photoemission activity and thermal stability to be used both in passive and active (transistor) light emitting devices. Materials and technologies involved are addressed to large consumer-markets such as automotive, information displays and lighting. Specifically advanced mesoporous films and new photonic nanostructures will be demonstrated along with their application to automotive display and info panel devices.

The light emitting devices developed in STABILIGHT will be characterized by all inorganic active layers and electrodes on the same plane. The light is emitted on both sides. These devices are designed to overcome the current limitations of OLED technology for automotive applications (low life-time at 80°C, very high investments, high cost because of the materials needed and relatively low yield because of the production complexity).
The active layer is characterized by a host conducting porous matrix with a network of well-organized nanocavities where luminescent semiconductor nanocrystals are embedded. The nanosized ordered cavities in the form of a mesoporous film will be grown on substrates which can be either thin glass or nanocomposite polymeric materials with tuned bulk and surface properties with the addition of inorganic fillers (e.g. layered silicates). The porosity of the film will be tuned so as to trade off high light efficiency against reduced complexity of the device. The development of novel inorganic nanostructured materials having superior quality, reliability, sustainability and cost-effectiveness will allow an optimal incorporation into new nano-photonic devices. The proposed products and technological solutions are alternative to displays based on both organic and inorganic LEDs, which are mostly developed outside Europe.
