Abstract The (Eu3+,Nd3+) co-doped lead fluorosilicate glasses (SKNPfLfEu/Nd: 45SiO2+20K2O +5Na2O+(19-x)PbF2+10LiF+1.0Eu2O3+xNd2O3, here, x = 3.0, 2.0, 1.0, 0.5, 0.1, 0.05 and 0.01 mol %), were made by melt quenching technique. These glasses have been described through XRD, physical, optical absorption and decay rates along with luminescence results. The emission spectra of the present glass have been premeditated under 394 and 808 nm excitation. The observed emission intensities of transitions in co-doped glasses are stronger than that of single doped glass, which authenticate the energy transfer (ET) mechanism. The lifetime for both the 5D0 state (Eu3+) and 4F3/2 state (Nd3+) of co-doped glasses are found to shorten with increase in concentration compared to single doped glass. The ET efficiency has been calculated for all the concentrations of Eu3+ and Nd3+ ions. The obtained results suggested that the (Eu3+, Nd3+) co-doped glasses might be preferable than those of single doped one for photonic device applications.

用于增强光子器件应用的 (Eu3+,Nd3+) 共掺杂氟硅酸铅玻璃的光学特性

摘要 (Eu3+,Nd3+) 共掺杂氟硅酸铅玻璃 (SKNPfLfEu/Nd: 45SiO2+20K2O +5Na2O+(19-x)PbF2+10LiF+1.0Eu2O3+xNd2O3，这里，x = 3.0, 2.5,0, . , 0.05 和 0.01 mol %), 由熔体淬火技术制成。这些玻璃已经通过 XRD、物理、光学吸收和衰减率以及发光结果进行了描述。本玻璃的发射光谱已经在 394 和 808 nm 激发下进行了预谋。在共掺杂玻璃中观察到的跃迁发射强度比单掺杂玻璃强，这证实了能量转移（ET）机制。发现与单掺杂玻璃相比，共掺杂玻璃的 5D0 态 (Eu3+) 和 4F3/2 态 (Nd3+) 的寿命随着浓度的增加而缩短。ET 效率已针对所有浓度的 Eu3+ 和 Nd3+ 离子进行计算。获得的结果表明，(Eu3+, Nd3+) 共掺杂玻璃可能比单掺杂玻璃更适用于光子器件应用。
