Abstract

g-C3N4: Yb3+ composite has been prepared by a simple method using melamine and YbCl3 as raw materials. The introduced Yb3+ ions are composited with g-C3N4 and significantly cause the crystal lattice distortion in g-C3N4 , which is supported by first principles calculation and XRD patterns. The g-C3N4: Yb3+ composite can absorb blue-violet light and give near-infrared light at around 1 μm. Energy transfer sensitization from g-C3N4 to Yb3+ is demonstrated on the base of the excitation and emission spectra. The result refers a new approach for conversion of short wavelength light into near infrared emission..
