Improved photon management in a photoelectrochemical cell with Nd-modified TiO2 thin film photoanode

Optically Active TiO2:Er Thin Films Deposited by Magnetron Sputtering

“…Our previous research demonstrated improved performance of Ti(Nd)O 2 photoanodes in combination with external up-converting glass [ 30 ]. Excitation with near-infrared (NIR) radiation (λ exc = 940–980 nm), which results in the emission in the ultraviolet (UV) range (λ em = 340 nm), has led to a 13-fold increase in the photocurrent [ 30 ].…”

Synthesis, modification and application of titanium dioxide nanoparticles: a review

“…120 H 2 is the most ideal energy source in the future world, and thus an increasing interest in H 2 production under solar energy has been observed. 52,121 A series of strategies have been developed to transfer solar energy to laser light and split water to obtain H 2 on the surface of TiO 2 . 122 Apart from in gas production, TiO 2 -based materials have been widely used as photocatalysts in pollutant degradation.…”

Near-infrared to visible and ultraviolet upconversion in TiO2 thin films modified with Er and Yb

“…In our previous works, we investigated both the concepts of external 27 and internal upconverter, 28,29 and we demonstrated the possibility to use TiO 2 thin film photoanodes modified with rare earth ions (Nd 3+ , Er 3+ , Yb 3+ ) in photoelectrochemical cells. 27,29 Thin film photoanodes deposited at 20% O 2 /(O 2 + Ar) flow rate ratio exhibit the best photoelectrochemical properties (high value of photocurrent and rectangular shape of current density versus voltage curves).…”
