Introduction
Chalcogenide materials (CHG) are
compounds that contain one or
more elements from Group VI (16)
of the periodic table, specifically
sulfur (S), selenium (Se), and
tellurium (Te).
Results
The measurements were performed using Nicolet FT-IR (Fourier
Transform Infrared Spectrometer) with ATR Diamond. The
transmittance values were normalized against the air spectrum, as
baseline.

in group IV of the periodic table Figure 3: Transmission spectra measured for both ternary and
quaternary CHG materials.
Chalcogenide materials have gained significant interest in biomedical
applications due to their unique optical, electrical, and phase-change
properties. This research focuses on integrating chalcogenide thin
films into biosensors and optical imaging technologies, aiming to
enhance diagnostic accuracy, enable real-time imaging, and contribute
to the miniaturization of medical diagnostic devices.
Methods
Two glassy systems ternary and quaternary CHG were synthesized
from elements with 5 N purity by the conventional melt-quenching
method.
Discussion
Conclusion
CHG materials have outstanding infrared transmission, making
them essential for quick and non-invasive disease detection. By
adjusting their composition, like adding more Ge or introducing Te,
they can be tailored for better medical imaging, biosensors, and
real-time health monitoring, shaping the future of healthcare.
