论文摘要
多光子吸收（MPA）是一种非线性光学过程，涉及通过材料同时吸收两个或多个光子，以将其基态促进其基态至激发态。多光子吸收承诺许多重要的应用，例如多维荧光成像，三维（3D）数据存储。纳米尺寸半导体材料的物理和化学特性由于量子尺寸效应而发生了巨大变化。多光子吸收和量子效应的组合将是一项有趣的研究。半导体纳米材料的多光子吸收是一种令人兴奋的现象，可促进许多重要的应用。本文回顾了从基于粉红色的纳米材料到钙钛矿纳米材料及其在各个领域的应用。
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.
