At present, the most common materials for solar-blind UV light detectors are wide band-gap semiconductors, which generally have high requirements and complex methods for preparation. Ordinary semiconductor materials such as silicon, , and were industrialized, but they were excluded for direct harvest of solar-blind UV light due to their inability to absorb solar-blind light photons. Here, inorganic-organic hybrid film of :/ was used as a spectral converter to realize the detection of broadband solar-blind UV light by ordinary semiconductor, converting broadband solar-blind UV luminescence to visible luminescence based on down-conversion process, after which the visible luminescence was detected by the Si photo-resister. The results show that hybrid film based on rare earth luminescence materials is particularly valuable for broadband solar-blind UV detection.
目前，日盲紫外光探测器最常用的材料是宽带隙半导体，其通常对制备有很高要求且方法复杂。诸如硅等普通半导体材料实现了工业化，但由于它们无法吸收日盲光光子，因而被排除用于直接探测日盲紫外光。在此，采用：/的无机-有机杂化膜作为光谱转换器，以实现普通半导体对日盲宽带紫外光的探测，基于下转换过程将日盲宽带紫外光致发光转换为可见光致发光，之后由硅光电阻检测可见光致发光。结果表明，基于稀土发光材料的杂化膜对于日盲宽带紫外探测特别有价值。
