Forensic Studies and Display Analysis

Nanotechnology is a growing area of research primarily due to the numerous potential applications of new synthetic nanomaterials in engineering/science. It has been found that the physical properties of individual nanoparticles are different from those of their bulk counterparts. Nanostructured materials have attracted a great deal of attention in the past few years for their unique characteristics that cannot be obtained from conventional macroscopic materials. Owing to quantum size effects and surface effects nanoparticles can display novel optical electronic magnetic and structural properties that might find many important technological applications. The importance of nanomaterials in the field of luminescence has increased especially as they exhibit enhanced optical electronic and structural properties. They have potential as efficient phosphors in display applications such as new flat panel displays with low-energy excitation sources solar energy converters optical amplifiers and thermoluminescent dosimeters. Phosphors are important materials for modern technology because of their ability to convert incident electromagnetic radiation into light.
