摘　　要：Energy-intensive technologies and high-precision research require energy-efficient techniques and materials.Lensbased optical microscopy technology is useful for low-energy applications in the life sciences and other fields of technology,but standard techniques cannot achieve applications at the nanoscale because of light diffraction.Farfield super-resolution techniques have broken beyond the light diffraction limit,enabling 3D applications down to the molecular scale and striving to reduce energy use.Typically targeted super-resolution techniques have achieved high resolution,but the high light intensity needed to outperform competing optical transitions in nanomaterials may result in photo-damage and high energy consumption.Great efforts have been made in the development of nanomaterials to improve the resolution and efficiency of these techniques toward low-energy super-resolution applications.Lanthanide ion-doped upconversion nanoparticles that exhibit multiple long-lived excited energy states and emit upconversion luminescence have enabled the development of targeted super-resolution techniques that need low-intensity light.The use of lanthanide ion-doped upconversion nanoparticles in these techniques for emerging low-energy super-resolution applications will have a significant impact on life sciences and other areas of technology.In this review,we describe the dynamics of lanthanide ion-doped upconversion nanoparticles for superresolution under low-intensity light and their use in targeted super-resolution techniques.We highlight low-energy super-resolution applications of lanthanide ion-doped upconversion nanoparticles,as well as the related research directions and challenges.Our aim is to analyze targeted super-resolution techniques using lanthanide ion-doped upconversion nanoparticles,emphasizing fundamental mechanisms governing transitions in lanthanide ions to surpass the diffraction limit with low-intensity light,and exploring their implications for low-energy nanoscale applications.
