Description
技术领域
本发明属于荧光纳米材料领域,涉及一种硼和氮双掺杂的二硫化钼荧光材料的制备方法。
背景技术
二维石墨烯材料所具有独特的结构使其展现出低电阻率,高载流子迁移率以及高导热性和高透光率等优异性质,因此在微电子、储能器件、传感器、平板显示和太阳能电池等诸多领域具有广泛的应用前景。自发现以来,人们在石墨烯制备方法与应用方面付出了巨大努力。但是由于石墨烯是零带隙材料且有很高的漏电流,这大大限制其在微纳米电子光学方面的进一步发展。近几年,人们发现二维过度金属硫族化合物。如二硫化钼(MoS2)二硫化钨(WS2),结构与石墨烯类似,但具有自己独特的光电性质。
作为一种重要的层状纳米材料,二硫化钼以其独特的层状结构在润滑剂、催化、能量储存、复合材料等众多领域得到了广泛应用。更重要的是,相对于其它层状材料,二硫化钼存在可调控的能带间隙,随着二硫化钼厚度的降低,其带隙可以从1.2eV增加到1.8eV。当厚度减小到单层时,其由间接带隙半导体变成直接带隙半导体材料,其发光率大大提高,从而在光电器件领域有光明的应用前景。
然而,虽然单层二硫化钼具有强烈荧光,但制备单层的二硫化钼非常困难,产量极低,制备条件苛刻且重复性低,如何大量制备高质量二硫化钼荧光材料是本领域急需解决的问题。
发明内容

(2)将混合粉末置于坩埚中,在氮气保护下进行煅烧,然后自然冷却;
(3)将步骤(2)所得粗产物进行洗涤,干燥后即可得到硼和氮双掺杂的二硫化钼荧光材料。
进一步,所述二硫化钼、硼酸和三聚氰胺的质量份数比为1:2-5:2-5。
进一步,所述超声处理的时间为0.5-20小时,功率为100-200W。
进一步,所述溶胶凝胶反应的温度为60-100℃,时间为0.5-48小时。
