Title: Morphological and photoluminescence study of chemically synthesized Al{sub 2}O{sub 3} polythiophene composite

Undoped and Al{sub 2}O{sub 3} doped Polythiophene were synthesized by chemical route method. All the samples were characterized by fourier transform infra-red spectroscopy. Scanning electron microscopy shows the formation of spherical like particles for Al{sub 2}O{sub 3} polythiophene composite and its size decreases continuously as Al{sub 2}O{sub 3} doping percentage increases. Photoluminescence spectra were recorded at excitation wavelength 325 nm. All the samples have mainly two visible peaks at 462 and 490 nm respectively. The PL of present sample may have several optoelectronic applications like organic light emitting diodes (OLEDs), and photovoltaic cell etc.
