Phase transition mechanism and application of silicon-doped VO2 thin films to smart windows

VO2 Nanoparticles‐Based Thermochromic Smart Windows

“…Zou et al synthesized Silicon (Si)-doped VO 2 samples with different Si concentrations by the sol-gel method. [60] The results show that with the increase in Si doping level, the thermochromic properties can be improved with a slight increase of τ c . This can be attributed to the simultaneous control of the transmittance of Si-doped VO 2 nanoparticles in the luminous and near-infrared regions.…”

Multifunctional thermochromic smart windows for building energy saving

“…VO 2 has always been the research hotspot in the eld of smart windows due to its reversible phase transition temperature with prominent optical changes to modulate solar incident light. However, the high phase transition temperature, 13 limited luminous transmittance, 45 and weak solar modulation ability 46 have restricted the development of VO 2 -based smart windows. Many strategies have been proposed to tackle these problems, including element doping, 46,47 multilayer lms, 48,49 nanocomposite lms, 50,51 and nano-/microstructural engineering.…”

The valence conversion mechanism for Mo‐doped VO2 films with enhanced thermochromic properties

“…As mentioned above, to achieve effective doping for improving the performance of VO 2 films, a rational designing of the preparation is crucial. [12][13][14][15] Previous studies mainly focused on the different deposition processes, such as pulsed laser deposition, vapor deposition, magnetron sputtering, and sol-gel method. [16][17][18][19] Among them, the sol-gel method with low cost, easy doping, and flexible control is a superior choice.…”
