In article number 2009796, Bo Zhou and co‐workers propose a novel simple migratory core–shell conceptual model for orthogonal upconversion. The red‐to‐green switchable output is easily achieved by dynamic control of the upconversion by altering the excitation wavelengths (e.g., 980/1530 nm) or using the non‐steady state excitation, showing great promise in the multi‐level information security.
