Development of low-phonon-energy glass for 3D volumetric display

This is the authors' abstract. We don't add key points for this paper.

Volumetric 3D display allows a wide range of applications in air traffic control, medical imaging, automotive and aerospace design, visualisation in weather or defence monitoring. Previous work in this area has examined the use of upconversion in low-phonon-energy fluoride glasses and single crystals as the imaging chamber material. However, these glasses and crystals are difficult to produce at a sufficient size and quality. We will report on our examination of a range of low-phonon-energy glasses. This study identified tellurite glass as a promising candidate with high fluorescence efficiency for display and up-scalability of the imaging chamber size.
