Stokes shift is an important feature of fluorescence, which reveals the energy loss between the excitation and the emission. For most fluorescent materials(e.g., organic dyes and proteins), the large overlap between the absorption and emission spectra endow them a small Stokes shift that induced reabsorption by fluorophore itself. Although the self-absorption can be effectively reduced due to the emergence of fluorescent nanomaterials, fluorescence attenuation is still observed in aggregated or concentrated nanocrystals, causing reduced sensitivity of biosensors. Therefore, increasing the Stokes shift can effectively improve the performance of nano-agents based biosensing. In this critical review, through understanding the Stokes shift from the viewpoint of self-absorption, the influence of Stokes shift on fluorescence properties are discussed. Based on the principle of changing the Stokes shift of fluorescent nanomaterials, we described the methods for constructing various optically large Stokes shift-based nanomaterials, and the application of these nanocrystals in biosensing is especially concerned in this review.

【目的】通过分析我国卓越农业期刊和农业领域高起点新刊的发展现状,探索我国农业期刊发展趋势,提出对我国农业期刊发展的启示,为我国农业期刊的高质量发展提供参考。【方法】以2019年入选“中国科技期刊卓越行动计划”(以下简称“卓越计划”)的19种农业期刊、2019—2023年入选“卓越计划”高起点新刊项目的农业期刊为研究对象,从卓越农业期刊优先建设的农业领域学科分布、期刊国内影响力、期刊国际影响力和农业领域高起点新刊的基本特征4个方面分析我国卓越农业期刊的发展趋势,并总结出对我国农业期刊整体高质量发展的启示及展望。【结果】与中国科协、中国科学院和农业农村部主管的农业期刊相比,教育部主管的农业高校所办期刊实力相对较弱,存在“强学科与弱期刊”现象,入选“卓越计划”的农业期刊数量较少。我国农业高校近年已在优势学科中全面布局,高起点新刊的数量呈上升趋势,同时通过挖掘交叉学科的空白领域,创办一批强劲新刊以逐步实现农业期刊与学科协同发展。【结论】我国农业领域虽然入选“卓越计划”的期刊数量较少,但优势学科明显,期刊发展动力十足,势头强劲,呈显著上升趋势。我国卓越农业期刊优先发展,将带动普通农业期刊共同发展。
