Solution-grown nanowires make efficient lasers

A team at the University of Wisconsin-Madison in the US has reported an effective technique for growing ultra-small lasers from perovskites. The result, disclosed today in Nature Materials, is a shortcut to lasers that are extremely efficient and able to create many colours of light.

"While most researchers make these perovskite compounds into thin films for the fabrication of solar cells, we have developed an extremely simple method to grow them into elongated crystals that make extremely promising lasers," says Song Jin, a professor of chemistry at the University of Wisconsin-...
