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..

Active accounts were imported to the new platform and assigned a random password by default. In order to access your account you need to access the login page and go through the Lost Password dialog (involves the system sending you an email with instructions) in order to reset your password. This step is necessary as passwords are kept in hashed form and the new platform uses modern hashing algorithms incompatible with the previous ones.
