英文摘要	vo2 (m) stf through reduction of v2o5 stf was prepared. the results illustrate that v2o5 stf can be successfully obtained by oblique angle thermal evaporation technique. after annealing at 550 degrees c/3 min, the v2o5 stf deposited at 856 can be easily transformed into vo2 stf with slanted columnar structure and superior thermochromic properties. after deposition sio2 antireflective layer, t-lum of vo2 stf is enhanced 26% and delta t-sol increases 60% compared with that of normal vo2 thin films. due to the anisotropic microstructure of vo2 stf, angular selectivity transmission of vo2 stf is observed and the solar modulation ability is further improved from 7.2% to 8.7% when light is along columnar direction. moreover, the phase transition temperature of vo2 stf can be depressed into 54.5 degrees c without doping. considering the oblique incidence of sunlight on windows, vo2 stf is more beneficial for practical application as smart windows compared with normal homogenous vo2 thin films.
