THE POWDER DIFFRACTION FILE: CURRENT DESIGN AND FUTURE DEVELOPMENTS

摘要

The Powder Diffraction File is the world's largest database for the structural characteristics of solid state materials. Since its founding in 1941, the PDF has been designed by ICDD's scientific membership and successive boards of directors to address the materials' identification needs of the community. In 2006, 2009, and 2012, the ICDD conducted global surveys of material and analytical scientists working with diffraction methods (see Figure 3). The purpose of the surveys are to continuously evaluate user needs, and track analysis methods and trends, having the ultimate goal of producing databases and educational services that are custom developed for the international community.
