ABSTRACT

Organic materials are held together by Vander Waals forces between molecules and are therefore ‘molecular solids. The consequence of this molecular nature is that the luminescence process in organic materials is associated with the excited states of molecules. Pure Fe³⁺ transition metal doped with Alq₃ Complexes synthesized by simple precipitation method at room temperature, maintaining stochiometric ratio. These complexes were characterized by XRD, and photoluminescence (PL) spectra. XRD analysis exhibits the poly crystalline nature of the synthesized complexes. The excitation spectra are in the range of 509 nm to 498 nm, and emission spectra in the range of 423 to 427 nm. Prepared organic phosphor is found in the nano range. It can be a suitable candidate for indigo-violet emitting OLED, PLLCD and solid state lighting applications.
