• contrast to nitrogen, phosphorus atoms are larger than carbon atoms. As a result, it has the potential to act as an n-type donor and create substitutional defects in the carbon cluster, changing the electronic and optical characteristics of CDs with great impact on polarizability, quantum yield, and

However, inevitable interfacial defects located at the interface of Gr/hBN heterojunctions, including point defects (single vacancies and substitutional defects) and topological defects can alter the electronic properties of Gr/hBN heterostructures and, consequently, the

• during the reaction process may distort the crystal structure and lead to an increase in the formation of substitutional defects, which may facilitate the incorporation of dopant ions into the system [36][37][38][39]. As an example, luminescent red Y(OH)3:Eu3+ phosphors were fabricated via employing this
