Dual-Emission Phosphors with Persistent Emission and Lanthanide Waveguides for Neuromorphic Photonics

The growing demands of big data and artificial intelligence have intensified the need for energy efficient and physically informed computing paradigms, motivating the development of brain-inspired neuromorphic architectures that emulate key principles of information processing in the human brain. Luminescent materials with persistent and stimuli-responsive emission provide attractive platforms for light-based information encoding, memory, and processing. Here, we explore two complementary material strategies for neuromorphic photonic computing: a dual-emission persistent phosphorescent layer and lanthanide-based luminescent waveguides. T
