Abstract
For the first time Lu2S3 (undoped and Pr-doped) single crystals were
successfully grown from melt using micro-pulling-down (mPD) technique.
Customization of halide mPD apparatus allowed us to grow rod-shaped ({\O}2 mm
and length around 20 mm) crystals of Lu2S3 with high melting temperature (~1750
{\deg}C). X-ray powder diffraction revealed that the grown crystals exhibit the
{\epsilon}-Lu2S3 crystal structure ({\alpha}-Al2O3 type, space group R-3c).
Optical and scintillation properties of both the undoped and Pr3+ doped Lu2S3
were investigated. Fast 5d-4f Pr3+ luminescence was observed in both
photoluminescence and radioluminescence spectra. The presented technology is an
effective tool for the exploration of a large family of high-melting sulfides.
Such materials show promise for application as scintillators, active laser
media, and optoelectronic components.
