Abstract

2D layered perovskites are recently emerged as one of the most promising materials for optoelectronics. These not only behave like a quantum well structures but also on doping Mn(II) ions at the Pb-site results highly emissive doped material. These structures can also be used as a starting material for obtaining 3D perovskites. Thermal treatment of Mn(II) incorporated layered perovskites in presence of Cs(I) ions led to Mn(II)-doped 2D platelets shaped perovskites, which also tune their dimensions with varying the dopant ion concentration. Keeping the importance of the 2D layered perovskites, this review focused on the basic structures to the recently developed synthetic strategies and their optical properties of layered structured perovskites, Mn(II)-doped layered perovskites and Mn(II)-doped 2D platelet shaped perovskites.

Highlights

Lead halide perovskite is typically known in the formula APbX3, where ‘A’ is a monovalent cation (Cs+/Rb+/methylammonium, formadinium, etc.), and ‘X’ is the halide ions
Apart from this, the doped layered perovskites are used as the template for the preparation of 3D-doped perovskite nanocrystals, by the thermal treatment of layered perovskite and Cs+ precursor (Das Adhikari et al, 2018; Parobek et al, 2018). Keeping all these issues in mind, this review focuses on the recent synthetic development and the structural and optical properties of these doped and undoped layered perovskites and their use as a template for the preparation of 2D platelet perovskites
The mostly studied optical property of Mn(II) doping in 3D lead halide perovskite is CsPbCl3, which has the ideal bandgap to transfer an efficient amount of excitonic energy to the Mn dopant state, to get a characteristic spin flipped emission of Mn dopant that originated from Mn d-d states 4T1 to 6A1 transition (Liu et al, 2016; Parobek et al, 2016; Guria et al, 2017; Mir et al, 2017; Dutta and Pradhan, 2019)

Summary

Introduction

Lead halide perovskite nanostructures recently emerged as the most promising materials for photovoltaic and optoelectronic applications (Kojima et al, 2009; Kovalenko et al, 2017; Jena et al, 2019; Li and Yang, 2019; Smith et al, 2019), which possess very high absorption coefficient, can achieve near unity photoluminescence quantum efficiency in different colors, and can be efficiently doped for enhancing carrier transportation ability (Snaith, 2013; Kim et al, 2016; Di Stasio et al, 2017; Yong et al, 2018; Das Adhikari et al, 2019b; Dutta A. et al, 2019; Mondal et al, 2019; Park et al, 2019; Zhang et al, 2019).
