Abstract Barium lead alumino fluoro borate (BaPbAlFB) glasses doped with Dy3+ ions were prepared by using melt quenching technique and characterized using various spectroscopic techniques to understand their usage in photonic devices. The SEM and EDX spectral studies were performed on the as prepared glasses to understand the glassy nature and elemental analysis respectively. The weight loss in the BaPbAlFB glass has been studied by the TGA. Judd-Ofelt (J-O) theory has been applied to the measured oscillator strengths of the absorption spectral features to evaluate radiative parameters for the prominent emission transitions of Dy3+ ions in BaPbAlFB glasses. The photoluminescence (PL) spectral measurements show concentration quenching beyond 1.0 mol% of Dy3+ ions in the as prepared glasses. The decay profiles observed for higher concentration of Dy3+ ions in these glasses are well fitted to Inokuti-Hirayama (I H) model to understand the energy transfer mechanism involved in the as prepared glasses. The experimental lifetimes (τexp) measured from the decay spectral features are correlated with radiative lifetime (τR) values to understand the quantum efficiency (η) of the as prepared glasses. From the PL spectra, colorimetric parameters such as CIE coordinates, correlated color temperature (CCT) and yellow-to-blue (Y/B) intensity ratios have been estimated to understand the usage of these glasses in photonic devices such as white LEDs and lasers.

Dy3+离子掺杂钡铅铝氟硼酸盐玻璃的光谱研究

摘要 采用熔体淬火技术制备了掺杂 Dy3+ 离子的钡铅铝氟硼酸盐 (BaPbAlFB) 玻璃，并使用各种光谱技术对其进行表征，以了解它们在光子器件中的应用。对制备的玻璃进行 SEM 和 EDX 光谱研究，以分别了解玻璃性质和元素分析。TGA 已经研究了 BaPbAlFB 玻璃的重量损失。Judd-Ofelt (JO) 理论已应用于测量吸收光谱特征的振荡器强度，以评估 BaPbAlFB 玻璃中 Dy3+ 离子显着发射跃迁的辐射参数。光致发光 (PL) 光谱测量显示，所制备的玻璃中 Dy3+ 离子浓度超过 1.0 mol% 时会发生浓度猝灭。在这些玻璃中观察到的更高浓度 Dy3+ 离子的衰减曲线非常适合 Inokuti-Hirayama (IH) 模型，以了解所制备玻璃中涉及的能量转移机制。从衰减光谱特征测量的实验寿命 (τexp) 与辐射寿命 (τR) 值相关，以了解所制备玻璃的量子效率 (η)。从 PL 光谱中，估计了 CIE 坐标、相关色温 (CCT) 和黄蓝 (Y/B) 强度比等色度参数，以了解这些玻璃在光子器件（如白光 LED 和激光器）中的用途. 从衰减光谱特征测量的实验寿命 (τexp) 与辐射寿命 (τR) 值相关，以了解所制备玻璃的量子效率 (η)。从 PL 光谱中，估计了 CIE 坐标、相关色温 (CCT) 和黄蓝 (Y/B) 强度比等色度参数，以了解这些玻璃在光子器件（如白光 LED 和激光器）中的用途. 从衰减光谱特征测量的实验寿命 (τexp) 与辐射寿命 (τR) 值相关，以了解所制备玻璃的量子效率 (η)。从 PL 光谱中，估计了 CIE 坐标、相关色温 (CCT) 和黄蓝 (Y/B) 强度比等色度参数，以了解这些玻璃在光子器件（如白光 LED 和激光器）中的用途.
