科研项目

1、脉冲强磁场下稀土荧光材料发光机理研究

主要以EuErDyTb等稀土离子组成的荧光材料为研究对象,包括掺杂材料如上述离子掺杂在YVO4YPO4NaYF4等常见的基质中形成的荧光材料,或者分子磁性材料。在强磁场下的研究可以获得激发态能级结构、晶体场对称性、自旋相关的荧光调制等信息和应用。

2、钙钛矿结构多铁材料光学二次谐波和磁致伸缩效应研究

ABO3钙钛矿结构的铁氧化物和锰氧化物由于其晶体结构和磁性离子决定的特殊的离子间电、磁相互作用而展现出多铁效应。主要利用光学二次谐波/光克尔对材料内部或表面磁化/电极化的敏感响应,研究此类多铁材料的磁畴、电畴的微观演化规律以及各向异性。并利用磁致伸缩研究此类材料中的自旋-晶格相互作用,从而揭示多铁相形成的机理。

3、贵金属/半导体复合结构非线性效应及超快响应特性研究

主要研究以氧化锌、金、银为代表的各类半导体、贵金属纳米材料的二阶和三阶非线性光学效应,通过构造多层膜、掺杂、复合结构等方式实现非线性极化率的增强,旨在将其应用于光器件领域。

4、二维材料及器件的光、电、磁特性及载流子弛豫过程研究

主要研究原子层材料的激子发光,拉曼散射,光电导及磁光响应特性。利用范德华力耦合和层间转移技术制作异质结器件,并研究其光学、电学及磁学性能。

5、半导体微腔中光子-电子态的耦合效应及其器件应用

光学微腔是调控半导体纳米结构发光性能的重要手段,通过光子-电子态的耦合效应,可以显著改善半导体结构的光学性能。在此,我们主要研究微腔中的受限光子与半导体激子之间的强耦合、弱耦合效应。尤其是强耦合所形成的激子极化激元,其光学性质及强磁场条件下的非线性效应,是我们关注的重点。
