Ultraviolet matrix‐assisted laser desorption/ionization (MALDI) is among the most popular soft ionization methods in mass spectrometry. Several theoretical models have been proposed to explain the primary ion generation in MALDI. These models require knowledge of various matrix molecular parameters for simulation. One such parameter is fluorescence quantum yield. However, the fluorescence quantum yield reported in previous studies remains controversial.

紫外基质辅助激光解吸/电离中使用的基质的荧光量子产率。

紫外基质辅助激光解吸/电离（MALDI）是质谱法中最流行的软电离方法之一。已经提出了几种理论模型来解释MALDI中的一次离子生成。这些模型需要了解各种基质分子参数才能进行仿真。这样的参数之一是荧光量子产率。然而，先前研究中报道的荧光量子产率仍存在争议。
