      abstract     = {Colloidal semiconductor nanocrystals are promising
                      materials for classical and quantum light sources due to
                      their efficient photoluminescence (PL) and versatile
                      chemistry. While visible emitters are well-established,
                      excellent (near-infrared) sources are still being pursued.
                      We present the first comprehensive analysis of
                      low-temperature PL from two-dimensional (2D) PbS
                      nanoplatelets (NPLs). Ultrathin 2D PbS NPLs exhibit high
                      crystallinity confirmed by scanning transmission electron
                      microscopy, revealing Moiré patterns in overlapping NPLs.
                      At 4 K, unique PL features are observed in single PbS NPLs,
                      including narrow zero-phonon lines with line widths down to
                      0.6 meV and a linear degree of polarization up to $90\%.$
                      Time-resolved measurements identify trions as the dominant
                      emission source with a 2.3 ns decay time. Sub-meV spectral
                      diffusion and no inherent blinking over minutes are
                      observed, as well as discrete spectral jumps without memory
                      effects. These findings advance the understanding and
                      underscore the potential of colloidal PbS NPLs for optical
                      and quantum technologies.},
