Title

Neutron scattering experiment on non-linear optical materials

Abstract

Recently a new class of molecular materials has been found which exhibits strong non-linear optical effects: Irradiating the sample with a low power IR Laser produces a broad and continuous light spectrum covering the visible regime. This emitted white light is highly directional and has a brilliance comparable to a Laser. The origin of this effect is, as of yet, unknown. This White-Light Emission (WLE) only occurs in amorphous samples while in a crystalline state these materials exhibit the well known Second Harmonics Generation (SHG) effect. These observations suggest that the WLE effect is linked to the amorphous structure. We propose neutron diffraction experiments to gain information on the structural cause of the WLE effect.
