Since 2014, nanoplatelet light-emitting diodes (NPL-LEDs) have been emerged as a new kind of LEDs. At first, NPL-LEDs are mainly realized by CdSe based NPLs. Since 2016, hybrid organic-inorganic perovskite NPLs are found to be effective to develop NPL-LEDs. In 2017, all-inorganic perovskite NPLs are also demonstrated for NPL-LEDs. Therefore, the development of NPL-LEDs is flourishing. In this review, the fundamental concepts of NPL-LEDs are first introduced, then the main approaches to realize NPL-LEDs are summarized and the recent progress of representative NPL-LEDs is highlighted, finally the challenges and opportunities for NPL-LEDs are presented.

“…Colloidal CdSe nanoscrolls were obtained using the technique described in [49,50], which was somewhat upgraded. The difference is that the selenium precursor was a 1-M solution of selenium in trioctylphosphine (TOP - Se) rather than a 0.1-M solution of selenium in octadecene (Se - ODE).…”

“…The difference is that the selenium precursor was a 1-M solution of selenium in trioctylphosphine (TOP - Se) rather than a 0.1-M solution of selenium in octadecene (Se - ODE). The replacement of the selenium precursor in the synthesis of quasi-twodimensional CdSe nanostructures makes it possible to significantly increase their longitudinal size (up to 150 nm, in contrast to the previously synthesised nanoplatelets with a longitudinal size of 50 nm; see [49,50]). It is energetically favourable for thin (of few atomic layers) planar structures with such a large longitudinal size to roll into a tube, as a result of which CdSe nanoscrolls are formed.…”

Nanostructures in the form of 1.2-nm-thick colloidal CdSe nanoplatelets rolled into scrolls are investigated. The morphology of these scrolls is analysed and their basic geometric parameters are determined (diameter 29 nm, longitudinal size 100 -150 nm) by TEM microscopy. Absorption and photoluminescence spectra of these objects are recorded, and the luminescence decay kinetics is studied. It is shown that the optical properties of CdSe nanoscrolls differ significantly from the properties of CdSe quantum dots and that these nanoscrolls are attractive for nanophotonic devices due to large oscillator strengths of the transition, small widths of excitonic peaks and short luminescence decay times. Nanoscrolls can be used to design hybrid organic -inorganic pure-color LEDs with a high luminescence quantum yield and low operating voltages.

“…Nanoplatelets continue to reveal new unique features, such as narrow emission bands, very small Stokes shifts, and ultrafast charge carrier recombination . New possibilities for using these features in a wide range of practical applications are being reported . Meanwhile, in most cases, it is not the nanocrystals themselves that are used but various heterostructures based on them …”

The current direction in the evolution of 2D semiconductor nanocrystals involves the combination of metal and semiconductor components to form new nanoengineered materials called nano-heteroplatelets. This Review covers different heterostructure architectures that can be applied to cadmium chalcogenide nanoplatelets, including variously shaped shell, metal nanoparticle decoration, and doped and alloy systems. Here, for the first time a complete classification of nano-heteroplatelet types is provided with recommended notations and a systematization of the existing knowledge and experience concerning heterostructure formation techniques, addressing the morphology, optoelectronic and magnetic properties, and novel features of different heterostructures. This Review is also devoted to possible applications of these heterostructures and of one-component nanoplatelets in multiple fields, including light-emitting devices and biological imaging.
