Intense visible photoluminescence is observed in Yb 0.7 Tb 0.3 (PFBS) 3 (PBFS = perfluorobutane‐sulfonate) coordination polymers upon IR excitation as a result of cooperative up‐conversion (UC) processes. These occur when two individually excited Yb 3+ ions simultaneously combine their energy into a high‐energy excited state of Tb 3+ .
