BACKGROUND The Information Age was founded on the semiconductor revolution, marked
by the growth of high-purity semiconductor single crystals. The resultant design and …

Nanocrystals (NCs) discussed in this Review are tiny crystals of metals, semiconductors,
and magnetic material consisting of hundreds to a few thousand atoms each. Their size …

We report for the first time on a hole conductor-free mesoscopic methylammonium lead
iodide (CH3NH3PbI3) perovskite/TiO2 heterojunction solar cell, produced by deposition of …

The detection of photons underpins imaging, spectroscopy, fibre-optic communications and
time-gated distance measurements. Nanostructured materials are attractive for detection …

A phosphor emitting both white light and broad near‐infrared (NIR) radiation can
simultaneously provide visual inspection and early signs of rotting of food products. The …

Summary" Go big or go home" could never be a truer statement, especially when it comes to
energy. The world population is increasing, the energy use per person is growing more …

Colloidal quantum dot (CQD) photovoltaics combine low-cost solution processability with
quantum size-effect tunability to match absorption with the solar spectrum. Rapid recent …

The field of photovoltaics is undergoing a surge of interest following the recent discovery of
the lead hybrid perovskites as a remarkably efficient class of solar absorber. Of these …

Colloidal quantum dots (CQDs) offer promise in flexible electronics, light sensing and
energy conversion. These applications rely on rectifying junctions that require the creation of …
