MANUFACTURING METHOD OF ALUMINATE SALT FINE PARTICLE LIGHT-ACCUMULATING POWDER

摘要

PROBLEM TO BE SOLVED: To industrially advantageously obtain an aluminate salt fine particle light-accumulating powder having a particle size favorable for dispersion in resins or coatings and exhibiting excellent light-accumulating characteristics. SOLUTION: A precursor comprising a double hydroxide comprised of an activating agent Eu, a co-activating agent R (wherein R is at least one element selected from the group consisting of Dy and Nd), Al and M (wherein M is at least one element selected from the group consisting of Ca, Sr and Ba) is prepared. The precursor is dry-baked to give the aluminate salt fine particle light-accumulating powder. COPYRIGHT: (C)2005,JPO&NCIPI
