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...
BCNO phosphors with Al3+ and Ti4+ doping were synthesized and their spectral properties were systematically investigated. The BCNO phosphors with Al3+ doping are mainly composed of amorphous Al2O3 and BCNO nanocrystal. The crystallinity of BCNO phosphors and intensity of B-N related chemical bonds are improved with Al3+ doping which leads to the enhancement of quantum yields from 5.6% to 63.4%. In...
