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.},
