Photophysical and structural aspects of perylene-doped 2-naphthol luminophors: Green emission by exciplex formation.

Several perylene (Pery)-doped 2-naphthol (2-NP) (Pery/2-NP) luminophors were prepared using conventional solid-state reaction techniques. Energy transfer in the excited state was examined using fluorescence spectroscopy and cyclic voltammetry. Fluorescence studies revealed exciplex formation by Pery in the form of structureless and broad spectra at higher concentrations with monomer quenching of 2-NP; a broad green emission was observed in the range 500-650 nm, peaking at 575 nm.

Synthesis of Highly Fluorescent D-A Based p-Terphenyl Luminophors and their Thin Films for Optoelectronic Applications.

The number of anthracene-tetracene (AN-TN) doped p-terphenyl (p-TP) luminophors [(TN-AN/ p-TP) (D-A)] and thin films of polystyrene doped p-TP luminophors were prepared at different proportion by conventional technique called solid state reaction and spin coating technique respectively. Excitation energy transfer (EET) was studied by fluorimetry and cyclic voltammetry technique. The result showed that, TN-AN/ p-TP in crystalline state as well as in thin films exhibit outstanding green emission at 475-550 nm, peaking at 525 nm.

Synthesis, Photophysical, Electrochemical and Thermal Investigation of Anthracene Doped 2-Naphthol Luminophors and their Thin Films for Optoelectronic Devices.

A series of novel luminophors of 2-naphthol by doping anthracene were prepared using conventional solid state reaction technique. The photophysical, electrochemical and thermal properties were studied by Fluorescence spectroscopy, XRD, SEM, TGA-DSC and by Cyclic Voltammetry techniques. The thin films were characterized by Fluorescence spectroscopy.
