Tiray brings together a group of materials scientists and electronic & software engineers working together to apply new materials for Optoelectronic applications and to drive the development and transformation of X-ray FPDs.

Perovskite materials were first discovered in Calcium Titanate compound, and later used to refer to all substances with the same crystal structure. In recent years, Metal Halide-based Perovskite is a popular material frequently studied by academics, and is widely used in Photovoltaic, Displayand Detection applications based on its Compilable Components and Tunable Properties.

In X-ray Detection application, Petrovsky can be used as a scintillator to convert X-rays into visible light and carry out Indirect Detection. Tiray is currently using Perovskite as a scintillator to give full play to its characteristics of Strong X-ray Cut-off Capability, High Sensitivity, and Short Afterglow Time, and has achieved the expansion of mass production by means of the Low-cost and High-efficiency coating producting process.

Photon-counting Detectors identify and count the energy of X-rays at the photon level, improving spatial resolution and reducing radiation dose during patient examinations. Perovskite materials can also be used as photosensitive semiconductors that convert X-rays into electrons and perform photon counting detection.

The advantages of Photon Counting Detectors include High Sensitivity, High Resolution and Low Noise, which makes it widely used in medical imaging diagnostics, e.g., in imaging examinations such as tumour Radiotherapy and CT, where the flux density of the contrast agent can be measured to assess the treatment effect and tumour extent. In addition, PCD can be used in combination with other imaging techniques, such as PET and MRI, to further improve contrast quantification and diagnostic accuracy.

Tiray has mastered the Large-area Scratch Coating process and successfully suppressed the dark current level through grain boundary passivation. The photogenerated charge transfer capability (2.2╳10-3 cm2 V-1) has reached the leading level in the world, and the sensitivity has increased by 80 times compared with indirect detectors.
