The thermochromic characteristics of ITO/VO2 composite films on SiO2 nanospheres
As a promising thermochromic material for smart windows, VO 2 -based films have received extensive attention. To enhance the luminous transmittance ( T lum ) of thermochromic smart windows without seriously affecting the solar modulation efficiency (Δ T sol ), this paper prepared VO 2 films by rapid...

| description | As a promising thermochromic material for smart windows, VO
2
-based films have received extensive attention. To enhance the luminous transmittance (
T
lum
) of thermochromic smart windows without seriously affecting the solar modulation efficiency (Δ
T
sol
), this paper prepared VO
2
films by rapid thermal annealing of sputtered vanadium thin films on an ordered SiO
2
nanosphere array, and then the ITO as antireflection layer was deposited on VO
2
film by reactive magnetron sputtering. The surface morphology, crystal structure and optical transmittance of the films were characterized by Scanning Electron Microscopy, X-ray diffraction and UV–VIS–NIR spectrophotometer, respectively. The SiO
2
nanospheres provide continuous refractive index gradient, while the deposition of the ITO antireflection layer creates conditions for thin film interference, thereby synergistically reducing surface reflection in the VO
2
-based smart window. Compared with the planar VO
2
thin film (
T
lum
, 39.1%), the ITO/VO
2
/SiO
2
composite structure can significantly increase the
T
lum
from 39.1 to 55.5%, an increase of nearly 16.4%, while the Δ
T
sol
is basically unchanged. The results provide an effective strategy for improving the performance of smart windows. |
