Abstract: 
The vast optical nonlinearity of 1,3,5,7-tetraphenyladamantane (AdPh(4)) enables efficient frequency conversion. The observed spectrum depends heavily on the material's habitus. In particular, it shows nonlinear white-light generation when its powder form is irradiated in the near-infrared, similar to an analogous organotin sulfide cluster [(PhSn)(4)S-6]. In contrast, single crystals of AdPh(4) exclusively exhibit narrow-band second-harmonic generation, i.e., discrete conversion within the crystal, rather than spectrally broadband white-light emission. This shows that crystallinity restricts the nonlinear response to the symmetry-allowed higher-harmonics, in this case the even-numbered, second harmonic, and inhibits the quasi-continuum white-light emission. Using the diamondoid-based material significantly enhances compatibility with conventional production techniques using photorefractive polymers and is thus an important step towards the fabrication of all-integrated white-light emitting devices.
