“…e peak positions tended to shi to longer wavelengths as the PEI fraction was increased because the increased number of C atoms is resulted in variations in the BCNO band gap and caused shi s in the PL peaks. ese results were consistent with pieces of research previously published in the literature when PEG (Ogi et al, 2008) and TEG (Kaihatsu et al, 2010) were used as the carbon source.…”

“…Furthermore, a high exothermic peak was observed in the sample from the PEI (Figure 3). It is clear from research published previously in the literature that the combustion of an organic carbon source plays a critical role in the formation of the BCNO phosphor (Ogi et al, 2008;Wang et al, 2009Wang et al, , 2011Kaihatsu et al, 2010), with the heat of combustion being a particularly important factor. us, the higher exothermic energy provided by PEI also resulted in the generation of graphite in the BCNO sample ( Figure 2), which created a structural change in the BCNO phosphor.…”

“…BCNO phosphors were prepared from reagent grade boric acid (H 3 BO 3 ), urea (CO(NH 2 ) 2 ) and polyethyleneglycol with a MW of 20 000 (PEG 20 000) with the modified urea route as developed by O'Connor et al [22][23][24] The specimens were prepared by heating the mixtures of raw materials to 780…”

“…Recently, Okuyama and co-workers [22] reported a simple and useful synthetic route for BCNO phosphor with a high emission yield and wavelength-tunable emission, which paves the way for practical application of such a phosphor, despite the fact that the origin of emission is yet unclear. In addition we found in our previous investigation that the tunable emission of the BCNO compound has a long persistent character, which can be correlated with the presence of different forms of carbon-related defects [23].…”
