The solar-blind ultraviolet （UV） band has unique features， such as low background noise， strong local security， and excellent resistance to interference. These characteristics make it highly useful in specialized communication applications. However， silicon-based detectors face challenges， including low detection efficiency and poor responsivity to solar-blind UV light. To overcome these limitations， spectral conversion technology has been introduced. This approach converts high-energy UV photons into visible or near-infrared light， making it compatible with commercial silicon detectors. It also offers benefits like low cost， high stability， and mature manufacturing processes. This paper reviews recent progress in solar-blind UV detection based on spectral conversion. First， it explores the applications and classifications of detectors that use spectral conversion. Then， it highlights advancements in high-efficiency detection methods for solar-blind UV imaging and communication. Finally， it discusses the potential future developments of this technology， emphasizing its growing importance in the field.
