  Multiphoton absorption (MPA) is a nonlinear optical process that involves
simultaneous absorption of two or more photons by a material to promote its
ground state to an excited state. Multiphoton absorption promises many
important applications such as multi-dimensional fluorescence imaging, three
dimensional (3D) data storage. Physical and chemical properties of nanometer
sized semiconductor materials change drastically due to quantum size effect.
Combination of both multiphoton absorption and quantum effects will be an
interesting study. Multiphoton absorption of semiconducting nanomaterials is an
exciting phenomenon which promotes many important applications. This paper
reviews multi-photon absorption properties of different kinds of semiconducting
nanomaterials starting from chalcogenide-based nanomaterials to perovskites
nanomaterials and their applications in various fields.
