In this project, the fundamental photo- and spin physics of organic radical materials will be investigated towards molecular-scale electronics and quantum information technologies. Unlike most organic materials which contain all-paired electrons, the radicals' unpaired electron has a quantum mechanical property called spin which gives rise to magnetism and 'doublet' character. We have shown that their spin property can be combined with strong luminescence to make highly efficient organic light-emitting diodes for converting electricity to light: more efficient than non-radical counterparts that have been used to date. By utilising the radicals' luminescence, spin and magnetic properties, the student will explore novel functionality for combined optoelectronic and spintronic applications, towards opto-spintronics.

在这个项目中，将研究有机自由基材料的基本光和自旋物理学，以实现分子尺度的电子学和量子信息技术。与大多数含有所有成对电子的有机材料不同，自由基的未成对电子具有称为自旋的量子力学性质，从而产生磁性和“双重态”特征。我们已经证明，它们的自旋特性可以与强发光相结合，以制造高效的有机发光二极管，用于将电转换为光：比迄今为止使用的非自由基对应物更有效。通过利用自由基的发光，自旋和磁性，学生将探索光电和自旋电子学应用相结合的新功能，走向光自旋电子学。
