Gadolinium silicate crystal (GSO) can be used in a wide range of applications and the technology is still being upgraded.

Gadolinium silicate crystal, referred to as GSO, with the chemical formula Gd2SiO5, is an optical matrix material with excellent performance. It has the advantages of high energy resolution, short decay time, and high radiation detection accuracy. It is generally grown by the Czochralski method.

According to the “China’s Gadolinium Silicate Crystal (GSO) Industry Market In-depth Research and Development Prospects Forecast Report 2023-2028” released by the Industrial Research Center shows that gadolinium silicate crystals can be widely used in petroleum, nuclear industry, medical equipment, military industry and national defense. In the field of medical equipment, gadolinium silicate crystals can be used to manufacture PET detectors, the core component of PET (positron emission tomography). PET is an advanced nuclear medicine imaging equipment that can be integrated with CT or MRI to form PET/CT or PET/MRI. The imaging quality is higher and the disease diagnosis and treatment effect is better. The market penetration rate is gradually increasing, which is good for silicon. Development of gadolinium acid crystal industry.

The performance of gadolinium silicate crystals can be improved by doping with other elements, such as cerium (Ce), praseodymium (Pr), europium (Eu), ytterbium (Yb), terbium (Tb), etc. Gadolinium silicate crystals made by doping different elements have different properties and can be used in different scenarios.

Cerium-doped gadolinium silicate crystal (GSO: Ce) is a new type of scintillation crystal with high conversion efficiency for X-rays and γ-rays. It can be used in high-energy physics, nuclear physics, oil exploration, nuclear medicine, safety inspection and other fields. Compared with thallium-doped sodium iodide (NaI:Tl), cerium-doped gadolinium silicate crystal has a shorter decay time, higher energy resolution, and does not deliquesce; compared with bismuth germanate (BGO), cerium-doped gadolinium silicate crystal The light output efficiency is higher and the radiation resistance is stronger. Cerium-doped gadolinium silicate crystal has excellent comprehensive properties as a scintillation crystal and has great potential for future development.

Ytterbium-doped gadolinium silicate crystal (GSO: Yb) is a laser crystal that can be used as the gain medium of femtosecond solid-state laser; europium-doped gadolinium silicate crystal (GSO: Eu) has excellent thermal release performance, fast response speed, It has high sensitivity and can be used in fields such as cultural relic dating and radiation dose detection.
