系统研究了碳源对硼碳氮氧化物（BCNO）荧光粉颗粒光致发光（PL）性能优化的影响。使用不同Mw值的乙二醇、四乙二醇(TEG)和聚(乙二醇)作为有机源。当使用TEG时，BCNO荧光粉在365 nm激发下表现出高PL性能，量子效率高达60%。所制备的BCNO颗粒的发射光谱峰受碳源的Mw影响。另一项研究详细调查了碳/硼和氮/硼摩尔比对 PL 性能的影响。波长峰值范围从 380 nm（近紫外）到 570 nm（近红光）的发射光谱可以通过改变碳/硼或氮/硼比率来调整。
The effect of the carbon source on the optimization of the photoluminescence (PL) performance of boron carbon oxynitride (BCNO) phosphor particles was systematically investigated. Ethylene glycol, tetraethylene glycol (TEG), and poly(ethylene glycol) of various Mw values were used as the organic sources. When TEG was used, the BCNO phosphors exhibited high PL performance under excitation at 365 nm with a quantum efficiency of up to 60%. The emission spectrum peak of the prepared BCNO particles was affected by the Mw of the carbon sources. An additional study investigated in detail the effects of the carbon/boron and nitrogen/boron molar ratios on PL properties. The emission spectra with a wavelength peak ranging from 380 nm (near UV) to 570 nm (near red) could be adjusted by varying the carbon/boron or nitrogen/boron ratios.
