Czochralski crystal growth of Zn2Te3O8

Mesoscale Self-Assembly of Highly Luminescent Zinc Tellurite Nanoclusters

“…Because of the ease of crystallization from the glass matrix, the Zn−Te−O glass system is promising among the nonsilica materials, , and hence the structures and properties of ZnO-TeO 2 glasses have been well explored. − Most of the studies were focused on the glass formation from the molten mixture of ZnO and TeO 2 and the formation of crystals with different compositions during the time of cooling. The optical and electrical properties of ZnTeO 3 single crystals were reported by Nawash et al The thin films of Zn−Te−O alloys − were also well studied because of their interesting properties to form isoelectronic traps. As oxygen is a more electronegative atom among the group VI elements, it attracts electrons from the host materials when it is substituting Te sites in ZnTe, which is responsible for interesting optical properties. , In this paper, we have explored the synthesis and optical properties of ZnTeO 3 and Zn 2 Te 3 O 8 under varied experimental conditions.…”

ZnTeO 3 crystal growth by a modified Bridgman technique

“…This mole percentage was also selected because it produced the required crystal. When cooled down, the 40:60 goes through a peritectic transformation and forms more than one phase, but single crystals can still be grown at this transformation [14,15]. Table 1 shows several mole percentages of ZnO-TeO 2 powders that were tested for growth.…”

Crystal growth, luminescence, and scintillation properties of Zn2Te3O8 crystal for 0νββ decay search

“…The weighed materials were mixed well via the ball-milling technique, charged in an alumina crucible, and transferred to a furnace for sintering. Compared to the previous study by J. M. Nawash et al, 24 we focused on the single-crystal growth from a stoichiometric composition, i.e., 40 : 60 mol% of ZnO : TeO 2 with the appropriate sintering of the ZTO compound before initiating crystal growth. The prepared mixtures were sintered at 600 °C for 24 h, ground, and sintered again under the same conditions to achieve the homogenous synthesis of ZTO.…”

“…Using the ZTO seed, a small crystal with a diameter of 15 mm and height of 22 mm was grown at a pulling rate of 1 mm h −1 and rotation rate of 10 rpm. The grown crystal was cooled to room temperature for 48 h. Because of the insufficient information available, we could not directly compare our crystal growth conditions to that reported by J. M. Nawash et al 24 However, the successful growth of the ZTO ingot in this study can be attributed to the good thermal shielding, growth from a stoichiometric composition, appropriate synthesis of ZTO powder prior to crystal growth and crystal growth using a ZTO seed (obtained using a Pt bar).…”
