Luminescence thermometry has evolved into a powerful optical technique for remote and non-invasive temperature measurements, finding applications that range from materials science to biomedicine. Most of its implementations, however remain limited to two-dimensional measurements and are challenged by the strong scattering and absorption encountered in complex media such as biological tissues. In this work, recent efforts toward the development of volumetric luminescence thermometry are presented. The methodology combines near-infrared luminescent probes, spectrally-resolved imaging, tomographic reconstruction strategies, and artificial intelligence algorithms designed to extract quantitative information from highly distorted optical signals. We also discuss how volumetric temperature mapping may provide functional information inaccessible to conventional optical imaging approaches. The broader vision extends beyond thermometry toward multiparametric luminescence sensing, where temperature, oxygen concentration, pH, and other physicochemical variables could be simultaneously reconstructed in three dimensions.
