Abstract

Abstract: Organic Light Emitting Diode (OLED) has major applications in the field of displays, lighting and visible light communication. Due to the advantages of low cost, light weight, low power and high efficiency, flexible organic light emitting diode have attracted the interest of researchers all over the World. Flexible OLEDs are considered to be the best suitable candidate for next generation lighting devices. In this research, a new flexible and transparent substrate with an average transmittance of 60-70% in the visible region (300-700nm) is synthesized with the help of organic materials such as tetraphenylphosphonium modified lithium saponite (TPP-LiSA), Synthetic Saponite (SA) and N, N-dimethylformamide (DMF). The as-synthesized substrate exhibits refractive index as close as glass which makes this substrate to be used for flexible displays. Characteristics such as extinction coefficient (k), absorption of the synthesized substrate are also calculated.
