Wave Band Adjustable Infrared Filtering via Mott Transition of Nano Ti₂O₃

Abstract

The Mott transition of Ti 2 O 3 nano powders is systematically investigated. It is found that in the Mott transition of Ti 2 O 3 nano powders, the infrared transmittance declines gradually with temperature rising. The curves of the infrared transmittance at the highest and lowest temperature present a "trumpet" shape ranging from 13.3 to 5.9 mm in wavelength. The "trumpet" feature of nano Ti 2 O 3 can be applied to realize the large and adjustable wave band in infrared filtering. The filtering band covers from short to long wavelengths with temperature rising. The big difference in infrared transmittance at 13.3 mm is determined by grain size distribution.

“…XRD patterns of pristine Ti 2 O 3 (Figure S2) and Ti 2 O 3 nanoparticles (Figure a) show that the characteristic diffraction peaks at 23.81, 33.07, 34.76, 40.19, 48.74, 53.78, 61.25, and 62.32° are well indexed to (012), (104), (110), (113), (024), (116), (214), and (300) planes of Ti 2 O 3 (JCPDS no. 71-1045), − respectively. Both XRD patterns are similar and there are no other characteristic peaks that appear for the ball-milled sample.…”
