The current research paper presents the different synthesis approaches of lanthanum oxide (La2O3) and its applications in the field of sensors. Due to its superior structural stability at high temperatures, active surface sites, chemical, and optical properties with substantially influenced luminescence efficiency in the visible domain, Rare Earth Metal Oxide Semiconductors (REMOS) have seen an increase in demand in recent years. The excellent qualities of such materials have increased their use in the fields of technology, industrial, pollution prevention, and, in particular, the manufacture of sensors. La2O3 is one of the rare earth metal oxide semiconductors with the widest energy band gap (Eg= 4.3 eV) and lowest lattice energy, making it potentially more useful for a wide range of optical and electrical applications. In past decades, a large amount of research has been conducted on these materials to evaluate potential applications in the optical, electrical, optoelectronic, electronic, gas sensing and biological areas. The size, shape, and surface of the lanthanum oxide have a critical role in the response and performance of the devices in these applications, among other things. The future of La2O3 as a key material in modern research is also discussed.
