GAGG(Ce) (Gd₃Al₂Ga₃O₁₂:Ce) is a next-generation inorganic scintillator crystal designed for high-efficiency gamma-ray detection. It combines very high light output, fast decay time, excellent energy resolution, and outstanding mechanical and chemical stability. Compared with traditional scintillators such as NaI(Tl) and CsI(Tl), GAGG(Ce) offers significantly higher light yield, non-hygroscopic behavior, and improved durability, enabling compact detector designs without hermetic sealing. GAGG(Ce) exhibits strong gamma-ray stopping power due to its high effective atomic number and density, while its emission peak around 520 nm is well matched to SiPMs and PMTs, making it ideal for modern solid-state radiation detectors. We supply high-quality GAGG(Ce) single crystals with optical-grade polishing, tight dimensional control, and optional reflector or encapsulation options for research, medical imaging, and industrial radiation detection applications. Key Features Very high light output (~50,000–60,000 photons/MeV) Fast decay time (~90 ns) Excellent gamma energy resolution Non-hygroscopic (no hermetic sealing required) High density and effective Z Emission peak ~520 nm (ideal for SiPMs) Excellent mechanical and thermal stability Typical Applications Gamma-ray spectroscopy Medical imaging (PET, SPECT, CT research) Radiation monitoring and dosimetry Homeland security and nuclear inspection Industrial non-destructive testing (NDT) Scientific and laboratory radiation detectors Typical Properties Material: Gd₃Al₂Ga₃O₁₂:Ce (GAGG:Ce) Density: ~6.6 g/cm³ Light Yield: ~50,000–60,000 photons/MeV Decay Time: ~90 ns Emission Peak: ~520 nm Energy Resolution: ~5–7% @ 662 keV (typical) Hygroscopic: No Frequently Asked Questions — GAGG(Ce) Scintillator Crystal What is a GAGG(Ce) scintillator crystal? + GAGG(Ce) is a cerium-doped garnet scintillator known for its extremely high light output, fast response, and excellent gamma-ray detection performance. How does GAGG(Ce) compare with NaI(Tl)? + GAGG(Ce) offers higher light yield, faster decay time, better mechanical strength, and is non-hygroscopic, eliminating the need for hermetic sealing required by NaI(Tl). Is GAGG(Ce) suitable for SiPM-based detectors? + Yes. GAGG(Ce) has an emission peak around 520 nm, which matches very well with the sensitivity of modern SiPMs and solid-state photodetectors. Does GAGG(Ce) require hermetic encapsulation? + No. GAGG(Ce) is non-hygroscopic and can be used without sealed housings, simplifying detector design and reducing system cost. Do you offer custom sizes or detector assemblies? + Yes. We support custom crystal dimensions, surface treatments, and OEM detector assemblies for research and industrial applications. .dr-faq { max-width: 900px; margin: 60px auto; } .dr-faq__title { font-size: 24px; font-weight: 600; margin-bottom: 28px; } .dr-faq__item { border: 1px solid #e6e6e6; border-radius: 14px; margin-bottom: 14px; background: #ffffff; overflow: hidden; } .dr-faq__question { width: 100%; background: #ffffff; border: none; padding: 18px 22px; font-size: 16px; font-weight: 500; display: flex; justify-content: space-between; align-items: center; cursor: pointer; text-align: left; } .dr-faq__question:hover { background: #f7f7f7; } .dr-faq__icon { font-size: 22px; line-height: 1; transition: transform 0.25s ease; } .dr-faq__item.active .dr-faq__icon { transform: rotate(45deg); /* + → × */ } .dr-faq__answer { display: none; padding: 0 22px 20px; font-size: 15px; line-height: 1.6; color: #555; }
