Cover Story: A comprehensive review is presented of the developments and applications of liquid crystals in luminescent optical concentrator films. A liquid crystal host induces a control over the absorption and emission properties in the film, and this has allowed the development of novel strategies with such hosts to combat the surface losses, which is usually considered a key factor limiting the performance of these concentrators. These strategies are extensively reviewed along with the associated materials and techniques for film fabrication, while making strides in linking these efforts together into a coherent storyline over a time period of at least a decade. The review concludes with the future perspectives for these exciting optical concentrators, while acting as a useful guideline or a reference manual for making further contributions.
