AB  - A lanthanide-organic frameworks Tb (C<sub>2</sub>O<sub>4</sub>)(HCOO) (1) is synthesized via. hydrothermal methods&nbsp; (autogenous pressure) at temperature around 200&deg;C over a period of a week. Obtained single crystals are characterized by Elemental Analysis (EA), Single Crystal Powder X-Ray Diffraction SCPXRD as well as optical measurements were categorized by Photoluminescence (PL) experiments. The results showed crystals are pure and they exhibit the peak of crystalline orthorhombic Pnma group space. The PL emission spectrum has been monitored at 325 nm (pulsed laser He-Cd). Resulted green luminescence spectrum for the green luminescence emission for compound 1 was located at 544 nm attributed to (<sup>5</sup>D<sub>4</sub>&bull;<sup>7</sup>F<sub>5</sub> ) electronic transition. The noticeable&nbsp;emission intensity for the compound 1 indicated that the lanthanide organic frameworksare good candidate materials for electro-optical devices, Field Emission Displays (FEDs) and they have a potential application in solid-state light.
