New Light from Old Minerals: Scintillation in Engineered Willemite Compositions
Original language description
The glass samples from glass-forming area of the ZnO-Al2O3-SiO2 phasediagram were prepared by standard melt-quenching method at 1400–1600 °Ctemperature range for 10–12 h. The subsequent annealing with a heating ramp of5 °C/min to 850 °C yielded glass-ceramics nature of samples. X-ray diffractionmeasurements identified the presence of amorphous phase for as-preparedsamples and two crystalline phases, including monoclinic Zn2SiO4, andrhombohedral Zn2SiO4 (willemite), after annealing. The scintillation andluminescence properties of prepared glass and annealed glass-ceramics wereinvestigated by using the time-resolved luminescence spectroscopy. Therestoration of the intense UV emission peaking at around 360 nm under the X-rayexcitation (40 kV), overcoming the standard Bi4Ge3O12 scintillator intensity bymore than 160%, was discovered after annealing while as-prepared glass samplesexhibited negligible luminescence response to the X-ray exposure. Thecorresponding scintillation decay with leading component in sub-nanosecondscale was detected for annealed samples. The bandgap of willemite was estimatedfrom the photoluminescence excitation spectra to be at 5.85 eV,photoluminescence emission shows the band in UV region with correspondingphotoluminescence decay times spanning from units to tens of nanosecond. Theimpact of annealing conditions on the material´s structural and optical propertiesis discussed in detail.
