Citric acid was used as carbon source for the optimization of the photoluminescence (PL)
performance of boron carbon oxynitride (BCNO) phosphor. Citric acid was chosen as an
alternative carbon source because of its simple molecular structure, low decomposition
temperature, relative inexpensiveness, and environmental friendliness. The prepared
sample exhibited a single, homogeneous, and broad photoluminescence emission band
whose peak varied from near-UV (400 nm) to yellow-visible (500 nm) upon excitation at 365 …
