We have identified optimal conditions for the synthesis of highly sensitive MgB4O7:Dy thermoluminescent phosphor and examined the effect of alkali metals (lithium and sodium) as additional dopants that improve the performance of the thermoluminescent phosphor.
This paper examines the influence of uniform rotation of the crucible-melt-crystal system in a flat-bottom Bridgman geometry on the columnar silicon structure formed by a flat solidification front. We analyze the key features of heat exchange via natural convection using numerical simulation of experimental conditions of the growth of multicrystalline silicon from high-purity metallurgical-grade silicon.
