Abstract：Optical microcavities highly confine optical fields in microscales to boost the interaction strength between photonsand matters，which canbeusedasageneral structure for enhancement of florescence and Raman scattering in applications of trace-detection and optoelectronics.The development of nanomanufacturing techniques advances optical microcavities to higher quality factors and smaller mode volumes，by which several new physical phenomena in radiationand scattering processes are observed.Unfortunately，the performance of optical microcavities in fluorescence and Raman enhancement competitive to surface plasmonic resonances supported by metallic nanostructures is still challenging.Thehybrid structures integrating optical microcavities with metals or 2D materials are therefore proposed，opens up new opportunities to boostthe microcavity-enhancedradiationand inelastic scattering superior to traditional surfaceenhanced fluorescence and surface-enhanced Raman spectroscopy in a variety of applications.This article reviews the advancements in optical microcavity enhanced fluorescence and Raman spectroscopies over past two decades.It provides acomprehensive overview of the types and optical properties of optical microcavities，and deeply explores the enhancement mechanisms in the cuting-edge of the related studies.Finally， the prospects of optical microcavity enhanced fluorescence and Raman spectroscopy in development and future applications are summarized.
