HIGH EFFICIENCY LASER INSTALLATION FOR THE SYNTHESIS OF NANOSTRUCTURES FROM LIQUID PRECURSORS OF HIGH TOXICITY AND HAZARD BY THERMAL VAPORIZATION TO OBTAIN GAS PHASE AT TEMPERATURES HIGHER THAN THE BOILING TEMPERATURE LIMIT AND LOWER THAN THE DECOMPOSITION TEMPERATURE LIMIT, WITH AUTOMATIC PRECISION AND ACCURACY CONTROL OF TEMPERATURE UP TO 500°C AND HIGHLY REPRODUCTIBLE SYNTHESIS

摘要

The invention relates to an installation for the synthesis of nanostructures to be employed in electronics and medicine. According to the invention, the installation comprises a high-power COlaser, a beam transport system (2), a tight reaction chamber (3), an internal combustion chamber (4), a system (13) for monitoring the beam power optically aligned with the beam axis (14), an injector (5) for injecting the gaseous precursor mixture from a system (7) of supply with technological gas, a mass control system (10), a stage evaporator (8) for heating the technological gas and converting liquid and gaseous precursors into a liquid phase, a system (9) for the supply and mass control of the liquid precursor, some thermostating systems (6) for monitoring the mixture temperature, a filter (11) for retaining the nanostructured powder formed upon interaction between the gas mixture and the laser beam, a flap (12) wherethrough waste gases are conveyed into a chamber (15).
