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 frequency domain considerations of a transient process. Time-resolved emission spectra of Y₂O₂S:Tb and Y₂O₂S:Eu show that Tb³⁺ and Eu³⁺ undergo two and three different types of transient processes, respectively. These processes are assigned to transitions from ⁵D_j to ⁷F. Resolving power for time resolution is suggested as a new criterion for system evaluation and calculated for the frequency response and stroboscopic methods.
