摘要: Abstract In the context, rare earth (Gd, Y and Eu) coordination polymers with salicylic acid their nitrates were used as precursors for luminescent species, which composed polyacrylamide (PAM) to form interpenetrating polymeric network systems dispersing media. Through sol–gel process of silicate sources (tetraethyl orthosilicate, TEOS), multicomponent hybrid assembled then series submicrometer phosphors RE2SiO5: Eu3+ (RE = Gd, Y) synthesized after thermal decomposition. Both X-ray diffraction (XRD) scanning electronic microscope (SEM) show that these materials possesses size 80–200 nm. The photoluminescent properties exhibit characteristic red emission at 612 nm.
