Henri Becquerel was interested in phosphorescence because he was exploring the properties of luminescent materials, particularly in relation to the phenomenon of fluorescence. His fascination with how certain materials could emit light after being exposed to radiation led him to investigate the effects of sunlight on phosphorescent substances. This research ultimately contributed to his discovery of radioactivity, as he observed that some materials could emit radiation without an external energy source, leading to groundbreaking developments in the field of nuclear physics.
