Abstract
We collect 16 gamma-ray-loud blazars (seven BL Lac objects and nine flat-spectrum radio quasars) with both observed near-infrared and gamma-ray flux densities and find that the near-IR luminosity correlates better with gamma-ray luminosity than with X-ray. Possible constraints on the gamma-ray emission mechanism are discussed. We suggest that the gamma-ray radiation is probably created by inverse Compton scattering of the radiation from hot circumnuclear dust by beamed, ultrarelativistic electrons.
