Ti-doped tungsten trioxide electrochromic film can be prepared by sputter deposition method. Some experts use metal tungsten-titanium alloy (mass fraction of titanium is 6%) as the target, and deposit a titanium doped tungsten trioxide (WO3: Ti) film on a FTO transparent conductive glass substrate by pulsed DC power supply using a coating machine.

The experts used metal tungsten and tungsten-titanium alloy targets to prepare Ti-doping WO3 electrochromic film by pulsed DC reactive magnetron sputtering method.

Some experts used an ultraviolet-visible spectrophotometer to measure the optical contrast of a Li-doping tungsten trioxide electrochromic film before and after discoloration.

When it comes to electrochromism, especially inorganic electrochromic materials, many people think of tungsten trioxide, and some people think of doped tungsten oxide films, among which Li-doping WO3 films are also expected to occupy a place. Certainly, there are also some people who think of the electrochemical performance test of Li-doped tungsten oxide film.
