MRS Fall 2014

We pick out some of the highlights from MRS Fall 2014.

Upconversion: When two wrongs make a right

Upconversion anti-Stokes processes allows emitted photons with higher energy than the energy of the incident photons, which may greatly benefit photovoltaic and photocatalysis technologies.
