Frequency response method of high speed spectrophotometry for luminescent materials.

Abstract

A frequency response method for high speed spectrophotometry, which is characterized by simpler instrumentation and narrower frequency bandwidth than the stroboscopic method, is developed from freuency domain considerations of a transient process. Time-resolved emission spectra of Y(2)O(2)S:Tb and Y(2)O(2)S:Eu show that Tb(3+) and Eu(3+) undergo two and… (More)
