abstract = {The synthesis and control of properties of p-type ZnO
iscrucial for a variety of optoelectronic and spintronic
applications;however, it remains challenging due to the
control of intrinsic midgap(defect) states. In this study,
we demonstrate a synthetic route to yieldcolloidal ZnO
quantum dots (QD) via an enhanced sol−gel processthat
effectively eliminates the residual intermediate reaction
molecules,which would otherwise weaken the excitonic
emission. This processsupports the creation of ZnO with
p-type properties or compensationof inherited n-type
defects, primarily due to zinc vacancies underoxygen-rich
conditions. The in-depth analysis of carrier recombinationin
the midgap across several time scales reveals microsecond
carrierlifetimes at room temperature which are expected to
occur via zinc vacancy defects, supporting the promoted
p-type character of thesynthesized ZnO QDs.},
