Investigations of Organic Light Emitting Diode Materials


EMSL Project ID
1659

Abstract

This goal of this investigation is to study the characteristics of proposed organic light emitting diode (OLED) materials. A number of metal quinolates with be studied to determine the effects of chemical modification, process variables, and environmental factors on light emission. This work will be in conjunction with X-ray absorption studies being carried out at the ALS at LBNL. At the EMSL we will use small spot XPS follow composition and failure modes in both model and light emitting structures. An important ability in the later stages of the study is the capability of the EMSL to prepare the vapor deposited samples and transport the device into the analysis chamber without exposure to air or moisture. The small spot capabilities of the Quantum 2000 will allow the monitoring of the changes in composition of failed regions of the OLED as compared to adjacent undamaged devices.
