Abstract The quest for artificial light sources mimicking sunlight has been a long‐standing endeavor, particularly applications in anticounterfeiting, agriculture, and color hue detection. Conventional simulators are often cost‐prohibitive bulky. Therefore, the development of series single‐phase phosphors Ca 9 LiMg 1‐x Al 2x/3 (PO 4 ) 7 :0.1Eu 2+ (x = 0‐0.75) with sunlight‐like emission represents welcome step towards compact economical source alternatives. obtained by an original heterovalent substitution method emit broad spectrum spanning from violet to deep red. Notably, phosphor x 0.5 exhibits impressive full width at half‐maximum 330 nm. A synergistic interplay experimental investigations theory unveils mechanism behind due local structural perturbations introduced 3+ Mg , leading varied distribution Eu within lattice. Subsequent characterization organic dyes combining absorption spectroscopy convolutional neural network analysis convincingly demonstrates potential this portable photodetection devices. Broad‐spectrum testing empowers model precisely differentiate dye patterns. This points being ideal sunlight. Beyond demonstrated application, phosphor's utility is envisioned other relevant domains, including visible communication smart agriculture.

Abstract Full‐visible‐spectrum emission phosphors are promising candidates for next‐generation white light‐emitting diodes (WLEDs), overcoming the complex and high costs of traditional mixed phosphors. However, their practical application is hindered by low luminescence efficiency. In this regard, a generalization strategy developed that involves creating heterostructure interfaces to prevent detrimental energy transfer processes, thereby boosting The SrLiPO 4 /Sr 9 MgLi(PO ) 7 :Eu 2+ single‐grain prepared in work have achieved remarkable full‐visible‐spectrum efficiency, with record internal external quantum efficiencies 76.1% 56.2%, respectively. WLEDs encapsulated phosphor feature color rendering index (≈93.9), correlated temperature (≈3100 K), stable performance, indicating as‐synthesized excellent healthy lighting.
