以三聚氰胺和硼酸为原料,在水溶液中反应合成出纤维状C3N6H6(H3BO3)2先驱体,通过使其在高温氮气氛下热解制备出了富硼、氮BCN化合物.利用XRD、FT-IR、XPS、SEM、HRTEM等对热解产物进行了表征,采用FS测量了热解产物的室温光致发光光谱,研究了热解温度对产物及其光致发光性能的影响.结果表明,1000℃以上热解均可制备出乱层石墨结构富硼、氮BCN化合物.随热解温度的升高,BCN化合物中的B、N含量逐渐增大,C含量逐渐减小.BCN化合物的晶体形状为棒状或纤维状,由相互交织的平均直径在2nm左右的纳米纤维构成.这些BCN化合物均为宽带隙半导体,在340～450nm和670～705nm出现了两个很强的呈明显宽化的光致发光峰,且随热解温度的升高,短波长的发射峰波长基本呈逐渐减小的变化趋势.
