Abstract
We prepared BCNO phosphors with yellow and orange emission and investigated the effects of chemical bonds on luminescence and absorption properties for BCNO phosphors in solid phase, water, acid and alkaline solutions. The BCNO phosphors are mainly consisted of B‒N, C‒N, B‒O, C˭C, C‒H and N‒H chemical bonds, and the intensity and content of chemical bonds are related to the ratio of boric acid to glycine. The emission peaks of BCNO phosphors are red shifted from 559nm to 605nm with increasing ratio of boric acid to glycine (1:1 to 1:10). The range of excitation and absorption spectra are broadened with increased ratio of boric acid to glycine. In addition, the acid and alkaline solutions have different effects on excitation, emission and absorption spectra of BCNO phosphors. The changes of luminescence and absorption properties of BCNO phosphors are related to the regulation of surface states and chemical binding status of BCNO phosphors, which is originated from the variety of relative energy band structure.
