研究目的
Investigating the synthesis, photophysical, electrochemical, and thermal properties of novel luminophors of anthracene (AN) and tetracene (TN) doped biphenyl for their application in optoelectronic devices.
研究成果
The doping of anthracene and tetracene in biphenyl system shifts the fluorescence emission from blue region to green region considerably. The efficient two step excitation energy transfer is proposed from biphenyl host to AN and then to TN. XRD analysis confirms the homogeneous solid solution formation of host and guest material. SEM estimation reveals the average crystallite size of 140 nm. TGA-DSC analysis confirmed thermal stability of compounds. CV analysis showed that, tricomponent luminophors are promising candidates as n-type materials for Organic electronics. So, overall study confirms their use in Optoelectronic devices.
研究不足
The study focuses on the synthesis and characterization of biphenyl luminophors doped with AN and TN, but does not explore their performance in actual optoelectronic devices.
1：Experimental Design and Method Selection:
The series of solid solutions of biphenyl were prepared by conventional solid state reaction method. Different concentrations of AN and TN doped biphenyl solid solutions were prepared by using appropriate amount and mixing all in silica crucible with heating at the melting point of biphenyl.
2：Sample Selection and Data Sources:
Biphenyl, anthracene and tetracene of scintillation grade were purchased from Merck-Schuchardt and used as received.
3：List of Experimental Equipment and Materials:
JOBIN YVON Fluorolog-3-11spectrofluorimeter, Philips Diffractometer (PW-3710 model, Holland), TA Inc. SDT- 2790, FEI Quanta FEG 200 -Scanning Electron Microscope.
4：Experimental Procedures and Operational Workflow:
The melt thus obtained was cooled to get polycrystalline luminophors of AN and TN doped biphenyl. The fine powder of doped biphenyl luminophors were then subjected to photophysical, thermal and electrochemical characterization.
5：Data Analysis Methods:
Classical Sherrer formula has been used to estimate the average grain size of biphenyl luminophors.
