Aerosol Assisted Chemical Vapor Deposition - AACVD

Among the liquid-source CVD techniques, the AACVD by the use of ultrasonic spraying allows an elaboration at atmospheric pressure under conditions leading to a very well controlled growth as illustrated by different growth type according to the experimental conditions:

- epitaxial growth [VO2/Saphir, SnO2/TiO2 ]

- controled texture [Cu2O] 

- 3D nanostructure – nanoflowers  [TiO2-].

The CVD technique is also versatile in terms of growth conditions and class of materials:

Improvement of luminescence properties by plasma or UV assisted deposition (optical amplification and spectral conversion of solar radiation)

Deposition of fluoride (YF3: Er) and oxyfluoride film highly luminescent by the use of fluorinated precursors.
