Abstract

Sn and Er2Si2O7:Yb co-doped SiO2 (SiO2-Sn/ Er2Si2O7:Yb) thin films were successfully fabricated by using the sol-gel method. The Er-related near-infrared (NIR) luminescence performance was significantly enhanced by improving the quality of nanocrystals and introducing the energy transfer process of Yb. The designed electroluminescent device based on SiO2-Sn/Er2Si2O7:Yb film achieved visible and dual-wavelength NIR electroluminescence (EL). The Er-related NIR EL integrated intensity of the optimal device increased by more than 2 times compared to the Yb-free device. The optimal ErYb silicate electroluminescent devices also exhibited excellent performance in threshold voltage (~22 V), power efficiency (

$\sim 2.6\times 10 ^{-3}$

), and operational stability (>600 min), which is promising for the development of efficient and stable silicon-based NIR light sources.

硅膜中Sn/ErYb硅酸盐共掺杂的高效稳定电致发光器件

采用溶胶-凝胶法制备了Sn和Er2Si2O7:Yb共掺杂SiO2 （SiO2-Sn/ Er2Si2O7:Yb）薄膜。通过改善纳米晶体的质量和引入Yb的能量传递过程，er相关的近红外发光性能得到了显著提高。所设计的基于SiO2-Sn/Er2Si2O7:Yb薄膜的电致发光器件实现了可见光和双波长近红外电致发光。与无yb器件相比，优化器件的er相关近红外EL集成强度提高了2倍以上。优选的ErYb硅酸盐电致发光器件在阈值电压（~22 V）、功率效率（$\sim 2.6\times 10 ^{-3}$）和工作稳定性（>600 min）方面均表现出优异的性能，为开发高效稳定的硅基近红外光源提供了良好的前景。

期刊介绍： IEEE Photonics Technology Letters addresses all aspects of the IEEE Photonics Society Constitutional Field of Interest with emphasis on photonic/lightwave components and applications, laser physics and systems and laser/electro-optics technology. Examples of subject areas for the above areas of concentration are integrated optic and optoelectronic devices, high-power laser arrays (e.g. diode, CO2), free electron lasers, solid, state lasers, laser materials'' interactions and femtosecond laser techniques. The letters journal publishes engineering, applied physics and physics oriented papers. Emphasis is on rapid publication of timely manuscripts. A goal is to provide a focal point of quality engineering-oriented papers in the electro-optics field not found in other rapid-publication journals.
