Semiconductor nanoplatelets (NPLs) are a class of nanocrystal with precise atomic thickness (1-2nm) and large lateral areas (hundreds of nm). Control over the number of monolayers (ML) in these materials offers exceptional control over their size-confined optical properties. Their unique morphology allows for interesting properties arising from their surfaces and lateral extent, but synthetic control over their lateral size has not been robustly explored in the literature. We demonstrate a controlled seeded growth for mesoscale CdTe NPLs (>1000nm), exploring parameters for optimization and in-situ monitoring to elucidate the mechanism of growth. Furthermore, using these mesoscale NPLs, we demonstrate correlated electron and optical microscopy to study single NPLs, drawing comparisons to 2D semiconductors.
