Abstract 25Li2O–05Gd2O3– 15PbO – (55-x) SiO2:x Sm2O3 (LPOSm) and 25Li2O–05GdF3- 15PbO – (55-x) SiO2:x Sm2O3 (LPFSm)glasses were prepared by melt quenching method. Optical, luminescence JO-parameters and radiative properties were studied using various techniques. While comparing Ω2 parameter values between LPOSm05 and LPFSm05, the LPFSm05 glass has more asymmetric environment around Sm3+-ions and more covalency between Sm3+-O bonding then LPOSm05 glass. Moreover, LPFSm05 has higher value of branching ratio than LPOSm05 showing its suitability for laser active medium. The current investigation reveals that value of IR/O-ratio for LPFSm05 is more than LPOSm05 showing its more asymmetric nature and more local disorder for Sm3+-ions than LPOSm05 glass. From evaluated results the CIE-color-coordinates for LPOSm and LPFSm glasses fall in orange region. The calculated value of prepared LPOSm and LPFSm glass are less than warm CCT (

Sm3+离子掺杂的Li2O-Gd2O3-PbO-SiO2和Li2O-GdF3-PbO-SiO2玻璃在橙色发射固态器件中的光学和发光特性的比较研究

摘要 25Li2O–05Gd2O3–15PbO–(55-x) SiO2:x Sm2O3 (LPOSm) 和 25Li2O–05GdF3-15PbO – (55-x) SiO2:x Sm2O3 (LPFSm) 玻璃是通过熔融淬火法制备的。使用各种技术研究了光学、发光 JO 参数和辐射特性。在比较 LPOSm05 和 LPFSm05 之间的 Ω2 参数值时，LPFSm05 玻璃在 Sm3+ 离子周围具有更多的不对称环境，并且 Sm3+-O 键合之间比 LPOSm05 玻璃具有更多的共价键。此外，LPFSm05 比 LPOSm05 具有更高的支化率值，表明其适用于激光活性介质。目前的调查表明，LPFSm05 的 IR/O 比值大于 LPOSm05，表明其比 LPOSm05 玻璃更不对称，Sm3+ 离子更局部无序。根据评估结果，LPOSm 和 LPFSm 玻璃的 CIE 颜色坐标落在橙色区域。
