LASER WRITING OF NANOMATERIALS FOR OPTOELECTRONIC DEVICES
Technology Readiness Level (TRL)
2
Innovations and Benefits
Production of nano-structures with controlled dimensions in solution and film in combination with polymers. The synthesis takes place thermally and / or induced by laser sources on film too. The laser writing applications of nano-materials are currently focused on applications for solid-state luminous devices (Organic Light Emitting Diode - OLED), but they can also be used in the photovoltaic and sensor field.
Use
Currently the synthesis of nano-particles takes place in solution and solid state (film) and the laser writing to be applied for the realization of light sources on solid state is being implemented.
The technology can also be applied in other areas such as the new generation photovoltaic systems.
Applications and ongoing Activities
The synthesis of nano-particles in solution by thermolytic way has already been implemented starting from some precursors both in solution and in solid state in combination with polymers.
The control of the chemical-physical properties of the nano-particles is obtained by modulating the reaction time and temperature, both in solution and solid state (polymeric film).
The optical characterization is being set up by means of UV-Vis spectroscopy, luminescence and fluorescence and structural microscopy by X-ray diffraction and transmission electron microscopy.
In parallel, the application of the laser writing methodology on OLED solid state devices is studied.
