Inorganic lead halide perovskites (ILHPs), an emerging
class of
semiconductors, hold great potential for a broad spectrum of applications,
ranging from solar cells and light-emitting diodes (LEDs) to scintillators
and lasers, due to ILHPs’ exceptional optical/electronic properties.
The properties of ILHPs are closely related to their micro-/nanostructures,
and thus controlling the micro-/nanostructures of ILHPs is highly
desired to promote further development. Self-assembly, a common but
powerful method, has recently been explored for the synthesis and
control of the micro-/nanostructures of ILHPs. In this Review, we
first summarize recent advances in the self-assembly of ILHPs into
micro-/nanostructures and pay attention to main factors that can influence
the self-assembly process. We then illustrate representative applications
of the self-assembled micro-/nanostructures of ILHPs, including photodetectors,
LEDs, lasers, and X-ray imaging. And last, we offer our perspectives
on the self-assembled micro-/nanostructures of ILHPs, particularly
their applications.
