摘要: Chemical dissimilarity of tellurium oxide with silica glass increases phase separation and crystallization tendency when mixed melted for making a glass. We report novel technique incorporating an Er(3+)-doped tellurite composition into substrates through femtosecond (fs) laser generated plasma assisted process. The engineered material consequently exhibits the spectroscopic properties Er(3+)-ions, which are unachievable in pure implies this as ideal integrated photonics platforms. Formation well-defined metastable homogeneous structure Er(3+)-ions network, modified has been characterized using high-resolution cross-sectional transmission electron microscopy (HRTEM). chemical structural analyses HRTEM, Rutherford backscattering spectrometry (RBS) excitation techniques, confirm that such fs-laser implanted glasses may be significantly higher concentration without clustering, validated by record high lifetime-density product 0.96 × 10(19) s.cm(-3). Characterization planar optical layers photoluminescence emission spectra were undertaken to determine their thickness, refractive indices properties, function Er(3+) via different target glasses. increased content enhance index intensity layer whilst lifetime thickness decrease.
