ABSTRACT
Accepted: 21 September 2020
The perovskite-based materials with optical tuning properties are very important for many practical applications such as the solid-state lighting technology, solar cell, and catalysis. In this work, we used the top-down method to prepare the two-dimensional (2D) (CH3(CH2)3NH3)2(CH3NH3)n-1PbnI3n?1 (CPI, n = 1, 2) hybrid perovskite quantum dots (QDs), and reported that the 2D CPI QDs featured an emission band covering the ultraviolet (UV) and blue region, with almost all the emission intensity in the UV region. This UV emission spectrum, along with the UV absorption spectrum, means a strong quantum confinement, as revealed by the X-ray photoelectron spectroscopy (XPS). In addition, the nonlinear optical scattering and absorption properties based respectively on the optical and photoacoustic z-scan characterizations were observed in the 2D CPI QDs, the results of which revealed a two-photon absorption coefficient of up to 6.5 9 102 cm/GW. This work reveal the potential of 2D CPI QDs in the high optical limiting applications.

1 Introduction Due to the tunable optoelectronic behaviors, the organic-inorganic halide perovskites have attracted great attention in the past years, and have exhibited a lot of potential applications in diverse fields, such as
the solid-state lighting technology [1], solar cell [2], photo- [3] and electrochemical-catalysis [4], laser [5], and photodetectors [6]. So far, the organic-inorganic halide perovskites with different optoelectronic properties can be achieved by different methods, such as cation-transmutation approach [1, 2],
