Facile synthesis and luminescence properties of tubular BCNO phosphor with orange emission assisted by bamboo fiber

Abstract

In this work, tubular boron carbon oxynitride (BCNO) phosphors with orange-emitting are synthesized by bamboo fiber assistance. The effects of different sintering temperatures on the structure, morphology, and photoluminescence (PL) performance of BCNO phosphors were investigated. The results revealed that with the increase of sintering temperature, compared with the BCNO synthesized without the template, the synthesized BCNO phosphor with bamboo fiber as template gradually becomes a hollow tubular structure. Meanwhile, when the sintering temperature is 700 ℃, the BCNO phosphor shows bright orange emission at 315 nm excitation wavelength, and the quantum yield (QY) is up to 75%. Moreover, the prepared BCNO phosphor has a sensitive and selective quenching effect on Fe3+ ion under 365 nm portable ultraviolet lamp irradiation. By using the obtained BCNO phosphor as a fluorescence labeling marker, the fingerprint recognition on the object surfaces also could be realized.
