Abstract

Photon cascade emission has been reported in Pr³⁺-doped SrAl₁₂O₁₉ system, providing a unique method for direct measuring the quantum efficiency of ³P₀ in this material. The ¹S₀→¹I₆ fluorescence intensity can be taken as a measure of the initial ³P₀ population. Thus the quantum efficiency of ³P₀ can be calculated using the intensity ratio of the total emission from ³P₀ and the emission of ¹S₀→¹I₆. The efficiency decreases as the concentration of Pr increases, indicating the effect of concentration quenching. The quantum efficiency is still substantially less than 100% even in dilute sample due to the thermal excitation of ¹I₆ and ³P₁ states.
