Bismuth Vanadate (BiVO4) PLD Target

Introduction to Bismuth Vanadate Thin Film

Bismuth vanadate (BiVO4) thin film is a type of material that has received significant attention due to its potential use in photoelectrochemical (PEC) water splitting for renewable energy production, solar energy conversion, and catalysis. Thin film deposition techniques, such as chemical vapor deposition (CVD), pulsed laser deposition (PLD), and sputtering, have been widely used to fabricate BiVO4 thin films with precise control over their thickness and microstructure.

Bismuth vanadate is a semiconductor with a narrow bandgap of about 2.4 eV, which allows it to efficiently absorb visible light. When exposed to sunlight, the electrons in the material become excited and can be used to generate an electrical current, which is the basis of PEC water splitting.

 It is a light absorber and efficient photocatalyst for water splitting, making it useful for various applications such as solar energy conversion, environmental remediation, and electrochromic devices.

Comparison to Similar Materials

BiVO₄ is often compared to other metal oxides such as titanium dioxide (TiO₂) and zinc oxide (ZnO) due to its similar properties as a photocatalyst. However, BiVO₄ has a narrower bandgap compared to TiO₂ and ZnO, which makes it more efficient in absorbing visible light. BiVO₄ also has a higher charge carrier mobility and a longer electron-hole lifetime, which makes it a more efficient photocatalyst.

Crystal Structure of Bismuth Vanadate Thin Film

BiVO₄ has a tetragonal crystal structure and belongs to the scheelite family of compounds. It has a space group of I41/amd and lattice parameters of a=b=5.451 Å and c=12.995 Å.
