Synthesis of RoHS-Compliant Fluorescent 2D Nanocrystals for Fabrication of Display Pixel

Project description

Advancing safe, high-efficient luminescent materials

Current luminescent materials limit progress in displays and lighting, especially in terms of colour range and efficiency. Traditional quantum dots struggle to achieve narrow emission peaks and high photoluminescence quantum efficiency (PL QE) while remaining safe for the environment. Supported by the Marie Skłodowska-Curie Actions programme, the SYROCO project aims to solve this by creating RoHS-compliant 2D core/shell nanoplatelets (NPLs) of ZnSe/ZnS and ZnTe/ZnS. These NPLs will produce vibrant colours in violet, blue, cyan, and green. The project will provide valuable insights into photoluminescence and push the boundaries of current materials, paving the way for new optoelectronic applications and offering significant career growth.

Objective

Through the SYROCO project, my objective is to successfully synthesize RoHS-compliant 2D core/shell nanoplatelets (NPLs) of ZnSe/ZnS and ZnTe/ZnS. These nanoplatelets will exhibit predetermined emission colors (violet, blue, cyan, and green), narrow emission peaks (below 15 nm), and near-unity Photoluminescence Quantum Efficiency (PL QE), characteristics that have not yet been achieved. This endeavor aims to introduce a novel generation of Cd-free luminescent NPLs while offering valuable insights into the mechanisms underlying photoluminescence broadening and quenching in 2D nanomaterials. By transcending the current limitations in color range and emission line width imposed by conventional colloidal quantum dots, this research will pave the way for groundbreaking materials suitable for displays, lighting, and other optoelectronic devices. The outcomes of this project are expected to significantly advance my academic career by providing me with unique experiences in the convergence of multiple disciplines and positioning me as an emerging leader in the field.
Achieving these objectives hinges on the supervisor's extensive expertise and my own diverse experience working with various colloidal NCs exhibiting strong emission characteristics, such as InP/ZnSe/ZnS, ZnCdTeS, ZnSe/ZnS, InAg(Cu,Zn)S/ZnS NCs, perovskite NPLs, and transition-metal dichalcogenide nanowires. Over the course of thirteen years, I have honed my skills through collaborations in different laboratories and with various supervisors and partners in the fields of physics (solid-state, optics), photonics, and chemistry (physical chemistry), focusing primarily on functional luminescent NCs. This diverse experience has equipped me with the necessary tools to tackle multidisciplinary challenges in the field.
