Özet

A new Er3+-cluster-based 2D coordination polymer with the formula {[Er(SSA)(H2O)(2)](H2O)}(n) (SSA = 5- sulfosalicylic acid), complex 1, has been successfully synthesized via hydrothermal method and structurally characterized by elemental analysis, FT-IR, UV, single crystal and powder X-ray diffraction. Complex 1 reveals the Erbium atom is coordinated to eight oxygen atoms by four symmetry-related SSA ligands and two coordinated water molecules to form a distorted square-antiprismatic geometry. The photoluminescence spectrum of the complex 1 display intense pink emission with CIE chromaticity coordinates (0.540, 0.250). The complex 1 emit NIR luminescence at 1535 nm, which corresponds to the I-4(13/2)-I-4(15/2) transition of Er3+ ion. Moreover, its full width at half maximum values is 113 nm. This complex can potentially be applied to polymeric erbium-doped optical amplifiers, planar waveguides or infrared OLEDs.
