    Abstract
    锰离子相对稳定的发光特性及锰掺杂荧光粉的成功使得人们对锰离子发光的研究热情不减.本文综述了Mn2+掺杂金属硫族簇基半导体中团簇结构、组分关联的Mn2+发光特性.金属硫族簇基半导体具有原子级的精确结构,为探究Mn2+发光的精确"构效关系"提供了理想模型.在Mn2+掺杂的金属硫族簇基半导体中,Mn2+附近键长和团簇组装方式的差异决定了Mn2+配位场强的变化,进而影响Mn2+发光波长的变化.在Mn2+掺杂的金属硫族纳米团簇中,Mn2+的聚集形式和聚集体中Mn2+的数量决定了Mn-Mn耦合相互作用的大小,直接影响Mn2+发光效率、寿命及激发特性.

    • Pretraining has recently greatly promoted the development of natural language processing (NLP)
    • We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
    • We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
    • The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
    • Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
