Short summary
We show 13C spin hyperpolarization using laser irradiation at room temperature in two different systems: 1. pentacene doped in organic crystals of benzoic acid and 2. nitrogen-vacancy (NV) color centers in microdiamonds. The 13C NMR signal was enhanced by a factor of > 3000 using pentacene and > 300 using NV centers as polarization sources. We analyze the pros and cons of these two systems and discuss their prospects for room-temperature enhancement of NMR signals.
