Synthesis of Novel Blue and Green Light Emitting 4-Nitrophenol Luminophors for Optoelectronics.

The number of anthracene (AN) and anthracene-tetracene (AN-TN) doped 4-nitrophenol (4-NP) luminophors (AN/4-NP and AN-TN/4-NP) were prepared at different proportion by conventional technique called solid state reaction. Excitation energy transfer was observed by fluorescence spectroscopy and cyclic voltammetry. 4-NP acts as an outstanding light emitting matrix. The effect of the donor emission was perceived by changing the dopant concentration; this showed that AN/4-NP and TN-AN/4-NP exhibit fluorescence emission ranging from blue to green i.e. in the range from 400 to 525 nm and 535-550 nm, respectively. Structural properties and thermal stability was studied by XRD, SEM and TGA-DSC techniques. The study reveals that the prepared materials show excellent properties which can meet the demands of optoelectronic devices as well as for light emitting devices.
