Color‐tunable luminescent materials based on α, ω‐diethyl malonate terminated polydimethylsiloxane (EP) and lanthanide ions are synthesized. The EP is synthesized from α, ω‐hydride terminated polysiloxane (HP) and diethyl allyl malonate via hydrosilylation reaction. The FT‐IR spectra, 1 H NMR, 13 C NMR, and GPC are used to characterize the structures of HP and EP. The obtained materials, which were synthesized by incorporating Eu 3+ (or Tb 3+ ) ions into EP, exhibit excellent narrow‐width red (or green) emissions. Moreover, when integrating heterometallic Eu 3+ /Tb 3+ ions into EP, the luminescence spectra of the complexes are composed of green and red emission. Color‐tunable luminescent materials are obtained by tuning the proportions of Eu 3+ and Tb 3+ ions.
