A unique method of material synthesis based on vacuum co‐deposition is reported. A Eu complex was formed by co‐deposition of bis(dipivaloymethanato)europium (Eu(DPM) 3 ) and 2,9‐dimethyl‐4,7‐diphenyl‐1,10‐phenanthroline (BCP), which both showed excellent volatility during vacuum deposition. Photoexcitation of the BCP led to intense emission from the Eu 3+ ions, verifying efficient exciton energy transfer and therefore complex formation.
