  Organic liquid scintillators have been used for decades in many neutrino
physics experiments. They are particularly suited for the detection of
low-energy neutrinos where energy and timing information is required. Organic
liquid scintillators exhibit advantages such as high light yield, cost
effectiveness, radio purity, and more. However, they also entail disadvantages,
most prominently a lack of vertex resolution and particle identification. In
recent years, various novel ideas have emerged to improve the performance of
organic liquid scintillators. In this review, novel approaches to organic
liquid scintillators in neutrino experiments as of 2022 are reviewed and their
prospects and applications compared.
