Abstract

In the current work, Eu³⁺ ions doped Alkaline Earth Alumino Borate (AEAlB) glasses were synthesized using melt-quenching method and evaluation of J-O parameters and other radiative properties from the photoluminescence (PL) spectra were reported for visible red laser applications. The luminescence spectra were measured with 394 nm excitation have eight luminescence peaks associated with the transitions “⁵D₁→⁷F₀ (509nm), ⁵D₁→⁷F₁ (537nm), ⁵D₁→⁷F₂ (556nm), ⁵D₀→⁷F₀ (580nm), ⁵D₀→⁷F₁ (592nm), ⁵D₀→⁷F₂ (614nm), ⁵D₀→⁷F₃ (652nm) and ⁵D₀→⁷F₄ (701nm)” in all the AEAlBEu glasses under investigation. The decay spectra were used to measure the experimental lifetimes, quantum efficiencies and non-radiative decay rates of AEAlB glasses. All parameters confirm the aptness of the AEAlB glasses for visible red laser applications.

利用碱土硼酸铝玻璃的红橙激光光谱评价Judd-Ofelt （J-O）参数和效率

本文采用熔淬法合成了Eu3+离子掺杂的碱土硼酸铝（AEAlB）玻璃，并通过光致发光（PL）光谱评价了其在可见红色激光中的J-O参数和其他辐射性能。在394 nm激发下，所有AEAlBEu玻璃的发光光谱均有8个发光峰，分别为5D1→7F0 （509nm）、5D1→7F1 （537nm）、5D1→7F2 （556nm）、5D0→7F0 （580nm）、5D0→7F1 （592nm）、5D0→7F2 （614nm）、5D0→7F3 （652nm）和5D0→7F4 （701nm）。利用衰减光谱测量了AEAlB玻璃的实验寿命、量子效率和非辐射衰减率。所有参数都证实了AEAlB玻璃适用于可见红色激光应用。
