Abstract

Scattered and total transmittance in the 360–870 nm wavelength range is compared for standard bronze and anomalous blue VO2 thin films. Optical measurements using an integrating sphere were made on five samples which include one standard bronze VO2 thin film and four anomalous VO2 films prepared by different techniques. The microstructures of these films are compared and optical constants are computed at 0.632, 0.694, 1.15, and 3.4 μm.
