Abstract :
As40Se60 glass is synthesised in ≤ 35 min via microwave heating in a domestic microwave oven (DMO). The DMO product is compared with arsenic selenide glass made by conventional resistive furnace melting which takes > 30 h to produce homogeneous chalcogenide glass. X-ray diffraction, transmission electron microscopy with selected area electron diffraction, analytical scanning electron microscopy optical microscopy and differential thermal analysis indicate that the DMO As40Se60 has similar properties to those of the conventionally melted As40Se60 glass. Fourier transform infrared spectroscopy and refractive index dispersion show slight differences. The DMO As40Se60 glass is patterned, using hot embossing, and is drawn to fibre.
