Abstract
Abstract Two-dimensional (2D) layers of transition metal carbides, nitrides, or carbonitrides, collectively referred to as MXenes, are considered as the new family of 2D materials for the development of functional building blocks for optoelectronic and photonic device applications. Their advantages are based on their unique and tunable electronic and optical properties, which depend on the modulation of transition metal elements or surface functional groups. In this paper, we have presented a comprehensive review of MXenes to suggest an insightful perspective on future nanophotonic and optoelectronic device applications based on advanced synthesis processes and theoretically predicted or experimentally verified material properties. Recently developed optoelectronic and photonic devices, such as photodetectors, solar cells, fiber lasers, and light-emitting diodes are summarized in this review. Wide-spectrum photodetection with high photoresponsivity, high-yield solar cells, and effective saturable absorption were achieved by exploiting different MXenes. Further, the great potential of MXenes as an electrode material is predicted with a controllable work function in a wide range (1.6–8 eV) and high conductivity (~104 S/cm), and their potential as active channel material by generating a tunable energy bandgap is likewise shown. MXene can provide new functional building blocks for future generation nanophotonic device applications.

Summary
Two-dimensional (2D) material families have been attracting extensive interest with the aim to impose new functionalities for electronic, photonic, optoelectronic device applications owing to their unique properties in a wide range of attributes. MXene has a great potential in optoelectronic and optical applications, because of its electronic and optical properties, such as the possibility of bandgap opening [88,89,90] and work-function engineering [68, 69] which can be diversely tuned by the selection of M and X elements and surface functional groups. This has, not yet been realized experimentally. This review is intended to bridge the gap between the major developments and future research directions for the applications of MXene in nanophotonic devices
