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.
