| Abstract | Light-emitting diode (LED) applications consist of various materials. One of the materials used is polymer. In this study, MEH-PPV known as poly[2-methoxy-5-(2'-ethyl-hexyloxy)-1, 4-phenylenevinylene] was used. The objective of this paper is to characterize the electrical and optical properties of MEH-PPV thin film by using sol-gel method. The scope is to study only the MEH-PPV thin film without implementation to any device. The MEH-PPV thin film thicknesses were varied from 10 to 100 nm. The experiment was started by stirring the sol-gel solution with toluene. The spin-coating technique was used to deposit the MEH-PPV thin film on a glass substrate. All samples were characterized using Atomic Force Microscopy (AFM), Surface Profiler, Two-point Probe, Raman PL Dispersive and UV-Vis Spectroscopy for the surface morphologies, thin film thickness, electrical and optical properties respectively. From the current-voltage (I-V) measurement, it show that symmetrical line plotted at low-voltage ranges. Moreover, the calculated conductivity was inversely proportional with the thin film thickness. The results from photoluminescence (PL) spectra showed that the intensity reached optimum peak at 38nm thickness and quenched for other samples. At 108 nm of thickness, absorption reached the highest peak compared to other samples of different thickness. The film was non-uniformed for the thickness at 134 nm, due to aggregation phenomenon. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
