“…The superior glass stability of multicomponent tellurites allows them to be prepared as bulk glass by melt quenching, drawn into optical fibers, and even remelted to form microspheres . Planar tellurite thin films, on the other hand, constitute the basic building block for on‐chip photonic devices such as waveguide amplifiers, light emitters, flexible photonic components, and acousto‐optical modulators. Multicomponent tellurite films have been prepared using sol–gel processing and laser ablation .…”

Multicomponent TeO 2 -Bi 2 O 3 -ZnO (TBZ) glass thin films were prepared using RF magnetron sputtering under different oxygen flow rates. The influences of oxygen flow rate on the structural and optical properties of the resulting thin films were investigated. We observed that thin films sputtered in an oxygen-rich environment are optically transparent while those sputtered in an oxygen-deficient environment exhibit broadband absorption. The structural origin of the optical property variation was studied using X-ray diffraction, X-ray photoelectron spectroscopy, Raman Spectroscopy, and transmission electron microscopy which revealed that the presence of under-coordinated Te leads to the observed optical absorption in oxygen-deficient films.P.
