摘要

固体中高效的反斯托克斯振动发光（ASVL）具有重要的科学和技术意义。然而，在非相干弱光激发下，在固体中实现高效的ASVL是具有挑战性的。在本文中，我们给出了在室温下微瓦连续波非相干光激发下Mn4+激活的K2SiF6微晶荧光粉的明显ASVL的实验证明。同时，在ASVL发光中显示出明显的声子共振增强效应。这些发现证明了固体中高效ASVL与传统双光子上转换发光相比的优势。

Efficient Anti-Stokes Vibronic Luminescence in Mn4+-Activated Fluoride Phosphors

Efficient anti-Stokes vibronic luminescence (ASVL) in solids is of both scientific and technological interest. However, it is challenging to achieve an efficient ASVL in solids under the excitation of incoherent, weak light. In this article, we present an experimental demonstration of a pronounced ASVL in Mn⁴⁺-activated K₂SiF₆ microcrystal phosphor under the excitation of microwatt continuous-wave incoherent light at room temperature. Meanwhile, a clear phonon resonance enhancement effect is demonstrated in the ASVL luminescence. These findings demonstrate the advantages of the efficient ASVL in solids compared with the conventional two-photon upconversion luminescence.
