Product Description

Thermoluminescent detectors (TLDs) are made of sapphire .


The Chernobyl catastrophe has shown that for radiation environmental control, ionizing radiation TLDs are the most promising. Sapphire-based structures have a number of advantages.

Their sensitivity to g -radiation is an order of magnitude higher than that of LiF(Mg, Ti) and allows registration of radiation doses on the level of 8 m Gy. Their sensitivity is independent of the dose in 10 −11 –10 −2 Gy·s–1 range.

For dosimetry the TL peak at 440 К, which is associated with the liberation of holes captured by impurity ions and their recombination upon reaching the valence zone, is used.

The value of the peak depends on the degree of anionic nonstoichi-ometry, which can increase up to 10 17 vacancy/cm 3 under the influence of reducing and annealing medium as well as doping by some elements.




Zhongju has break through the limitations of traditional crystals growth by Kyropoulos method, which is difficult to grow high-quality, large-size sapphire crystals. Currently 120kg high-quality sapphire crystals are produced stably, and the production capacity can satisfy the requirement of reliable supply.

We have the ability to produce much larger crystal, if customer has corresponding request. The maximum diameter of substrate or components could reach up to 12 inches.
