为了简化了AlN/C复合泡沫材料的制备流程, 本文采用复分解反应法制备AlN纳米材料, 并通过800℃退火处理使其在碳泡沫衬底上重结晶为六方相AlN纳米线. 通过形貌表征测试, 纳米线为表面光滑的长直形圆柱体, 直径约50 nm, 长度10 m以上, 在碳微球表面沿[001]方向生长. 同时, 采用VLS生长机理对纳米线的生长进行了解释. 对样品光致发光谱的研究表明, 中心波长423 nm处存在一尖锐发光峰且随温度升高发生明显的红移现象, 系C替N杂质能级跃迁发光所致. 样品在紫光波段具有良好的光致发光特性, 有望应用于光探测器领域.To simplify preparation process of AlN/C composite foam, AlN nanomaterials are prepared via double decomposition reaction and then 800℃ annealing process to recrystallize hexagonal AlN (h-AlN) nanowires on carbon foam substrate. Fore the morphology characterization it follows that, h-AlN nanowires with straight cylindrical morphology grow along the [001]direction on carbon microspheres surface and are about 50 nm in diameter and several micrometers in length. Meanwhile, the growth mechanism of nanowire is interpreted as vapor-liquid-solid(VLS) process. The photoluminescence(PL) spectrum of as-prepared sample also researched, and the results show that a sharp photoluminescence peak appears at 423 nm and shifts toward the red side with temperature increasing. The peak is attributed to the transition luminescence, owing to the substitution of C for N impurity energy level. The sample has good PL character in purple light band and is potential to be used the in photodetector field.
