Principles and Applications of Organic Light Emitting Diodes (OLEDs)explores the ways in which the development of organic semiconductor materials is opening up new applications in electronic and optoelectronic luminescent devices.

The book begins by covering the principles of luminescence and the luminescent properties of organic semiconductors. It then covers the development of luminescent materials for OLEDs, discussing the advantages and disadvantages of organic versus inorganic luminescent materials. The fabrication and characterization of OLEDs is also covered in detail,...

This thesis focuses on the fundamental problem of characterising partially coherent beams. The book describes several non-interferometric methods based on phase-space tomography for recovering the spatial coherence information of optical beams.
In the context of optical beams, partially coherent light provides numerous advantages over coherent light. From microscopy to optical communications, there are many disciplines that benefit from using partially coherent beams. However, their range of applications currently remains limited due to the complexity of extracting information. In...

This thesis reports on innovations in the design and direct synthesis of graphene-based woven fabric (GWF) and multi-layer graphene/porous carbon woven fabric films (MLG/PC) by means of chemical vapor deposition (CVD), using woven copper mesh and nickel mesh as the template. Further, it presents the successful applications of these materials as a platform for solar cells, super capacitors and sensors, making it especially of interest to researchers and graduate students in the fields of materials sciences, nanotechnology and renewable energy.
