| 摘 要： | 采用水热法,以十六烷三甲基溴化氨(C16TAB)作为表面活性剂,在填充度为75%和温度180℃的条件下,制备了ZnS:Mn的纳米发光粉体.利用激发光谱、发射光谱和透射电子显微镜对其光学特性和形貌进行了研究.实验发现,与未进行表面修饰的ZnS:Mn纳米粒子相比,ZnS:Mn纳米颗粒发光亮度增加数倍,而且随着表面活性剂浓度的增加,ZnS:Mn发光强度显著增强.当质量比m(C16TAB):m(Zn)=1:5时,发光强度达到最大,粒径分布均匀,呈球形,平均粒度为50 nm.

| Abstract: | ZnS:Mn nano-sized powders were synthesized by hydrothermal method,using C16TAB as surfactant,the fill factor was 75%,reaction temperature of 180 ℃.The optical properties and the morphology of ZnS:Mn are studied by exssion spectra,emssion spectra and transmission electron microscopy(TEM).The result indicated that the uncoated ZnS:Mn nanoparticles is much stronger than that in surfactant ones.With C16TAB concentration increasing,the luminescent intensity of ZnS:Mn grew strong.When m(C16TAB)∶m(Zn) was 1/5,the most luminescent intensity was achieved.It is found that the particles of ZnS:Mn exposed ferrite has an average size of 50 nm. |
