The growth and properties of Y admixed LuAG:Ce scintillating single crystal fiber fabricated by laser heated pedestal growth method

Xibin Wang et al.

Summary: Aluminum garnet crystal shows great potential in detecting high-energy photons and particles due to its good scintillation properties and its ease of preparation as a single crystal fiber array detector. Scintillating single crystal fibers of 0.2 at% Ce: Lu1-xYxAG (x = 0, 0.25, 0.5, 0.75, 1) were successfully prepared using the laser heated pedestal growth method. The addition of Y admixture resulted in a shift of the 5d1 energy level of the Ce3+ luminescence center to lower energy and the 5d2 energy level to higher energy. Photoluminescence decay and scintillation decay curves were fitted with single-exponential and double-exponential decay curves, respectively, indicating different luminescence mechanisms. The highest scintillation light yields of 32,457 Ph/MeV and 10,617 Ph/MeV were obtained from the horizontal-direction and longitudinal-direction sides, respectively, of the 0.2 at% Ce: Lu0.25Y0.75AG scintillating single crystal fiber, demonstrating its potential for application in High Energy Physics.

Emission-enhanced high-performance Al2O3-Ce: (Y, Tb)AG composite ceramic phosphors for high-brightness white LED/LD illumination

Yanna Tian et al.

Summary: Al2O3-Ce doped garnet composite ceramic phosphors (CCPs) are fabricated via solid-state reaction and exhibit excellent thermal quenching and luminous efficiency. The bidirectional energy transfer process between Ce3+ and Tb3+ enhances yellow light emission and lowers correlated color temperature (CCT). The Al2O3-Ce: (Y0.9Tb0.1)3Al5O12 CCPs show the best performance, with a 17% drop in luminous efficiency at 450 K and a luminescence efficiency of 262 lm/W when driven by a 2.24 W blue laser. The decrease in CCT with increasing Tb3+ content is significant for white LD lighting.

Hadron-Induced Radiation Damage in LuAG:Ce Scintillating Ceramics

Chen Hu et al.

Summary: LuAG:Ce ceramic scintillators have great potential in high-energy physics due to their low cost, bright light, and fast decay time. This study investigates the optical and scintillation performance of LuAG:Ce ceramic samples co-doped with Mg2+ and Ca2+, as well as their radiation damage induced by neutrons and protons. The results show that LuAG:Ce ceramic samples have excellent radiation hardness and lower radiation damage compared to LYSO:Ce crystals.

Effect of SiO2 introduction on luminescence properties of LuAG:Mn phosphor 2+

Chenyao Zhao et al.

Summary: Mn2+ doped LuAG phosphors with different contents of Si4+ ions were synthesized and their effects on crystal structure and luminescence properties were studied. The introduction of Si4+ not only improved the emission intensity, but also resulted in a red-shift in emission peak and broadening of spectra. Suitable content of Si4+ replacement weakened thermal quenching, making it a candidate for warm white LEDs.

Characterization of Ce,Ca:LuAG ceramic scintillators fabricated from co-precipitated powders

Jinling Cai et al.

Summary: Ce:LuAG and Ce,Ca:LuAG ceramic scintillators were prepared by vacuum sintering the powders synthesized using the co-precipitation method. The composition, thermal behavior, spectral, and scintillation characteristics of the precursors and ceramics were investigated. The results showed that the Ce:LuAG ceramics had higher light yield and relative intensity of the fast component compared to those prepared by the conventional solid-state reaction method. Additionally, the scintillation decay of the Ce,Ca:LuAG ceramics was accelerated with a LY(0.5 μs)/LY(3 μs) ratio of 93%.
