Study on Novel Method to Measure Luminescence Time Interval Between the Initial and Terminal of Light Emission in Frequency Domain

Abstract

In this paper, a novel method to measure the luminescence time interval between the initial and terminal of light emission in frequency domain is proposed. Under the condition that the time of excitation pulse is equal to the luminescence time interval between the initial and terminal of light emission, the energy of excitation is complete dynamically balanced by the light emission and the maximum luminescence intensity can be achieved. So the luminescence time interval between the initial and terminal of light emission can be expressed as (is the driving frequency which is corresponding to the maximum luminescence intensity). The luminescence time interval between the initial and terminal of light emission () of Alq3 (Tris-(8-quinolinolato)aluminum) is [s] measured using the novel method.
