“…Shabbir et al [18] synthesized a compound of Er2O3 and zinc oxide using the sol-gel method and then added molybdenum; they observed that the fluorescence intensity of Er2O3 was much higher than that of ZnO-Er2O3 and Mo@ ZnO-Er2O3 showing a higher recombination rate which was undesirable and reduced the efficiency. By developing the Er2O3 composite with ZnO, the fluorescence intensity decreased, which showed that ZnO suppressed charge recombination, increasing the photocatalysis efficiency of Er2O3 and improving its optoelectronic properties.…”

The present work reviews the results of the photoluminescence study of erbium-doped ZnO nanostructures synthesized by physical and chemical methods. ZnO is a semiconductor compound composed of zinc and oxygen atoms. It possesses a wide bandgap (3.37 eV) and is optically and electrically active. When ZnO is synthesized in the form of nanostructures, such as nanoparticles, nanowires, nanorods, nanotubes, or nanosheets, it exhibits enhanced properties compared to its bulk counterpart due to quantum confinement effects and a high surface-to-volume ratio. By controlling different parameters in the growth processes of erbium-doped ZnO nanostructures, materials can be synthesized for different applications such as sensors, optoelectronics, and energy harvesting.

“…To the best of our knowledge, the combination of Er 2 O 3 and TMOs has not been reported so far for OER. Er 2 O 3 possesses superior features, including high mechanical strength and thermal stability, a wide band gap, and substantial hardness, which make it suitable for many applications. − Additionally, the Er–O bond endows the catalyst with satisfactory electronic conductivity, further enhancing its potential as an electrocatalyst.…”

The search for an effective, stable, and economically viable electrocatalyst for water splitting to replace expensive noble catalysts remains imperative. This investigation evaluates the impact of erbium oxide (Er 2 O 3 ) on the oxygen evolution reaction (OER) activity of transition metal oxides (TMOs), including nickel oxide (NiO), cobalt oxide (Co 3 O 4 ), and iron oxide (Fe 2 O 3 ). Introducing Er 2 O 3 nanoclusters into TMO nanostructures produces a heterostructure interface between Er 2 O 3 and the active TMOs, leveraging Er 2 O 3 's unique 4f electron occupancy as an effective electronic modulator, thus enhancing its electrocatalytic activity. Findings reveal that the Er 2 O 3 and Fe 2 O 3 hybrid (ErFeO) exhibits the most promising OER activity, characterized by low overpotential and Tafel slope, exceptional durability relative to synthesized materials, and outperforming the commercial noble catalyst, RuO 2 . Consequently, ErFeO is a prospective electrocatalyst for OER applications.
