Understanding the Mechanisms and Enhancement of Photostimulated Luminescence by Nanoscale Design and Fabrication
EMSL Project ID
24805
Abstract
Photostimulated luminescence (PSL) has found extensive application in the radiation detection, dosimetry, and imaging fields. To date however, a detailed understanding of the underlying mechanisms responsible for PSL from conventional materials is incomplete. This lack of understanding has hindered the development of new materials with improved properties. We propose to use luminescence spectroscopy to understand the photo-physics of conventional and novel nanomaterials paying particular attention to the influences of interfaces and surfaces. Since PSL requires efficient charge trapping at defect or interface states, new materials engineered to take advantage of these states will be studied and evaluated. In addition, two novel techniques utilizing dielectric confinement and surface plasmon coupling will be implemented and studied to better understand the electronic processes following photo-excitation.
