YAG:Nd crystals as possible detector to search for and decay of neodymium

Abstract

Energy resolution, α/β ratio, pulse-shape discrimination for γ rays and α particles, radioactive contamination were studied with neodymium doped yttrium-aluminum garnet (YAG:Nd). Applicability of YAG:Nd scintillators to search for 2β decay and α activity of natural neodymium isotopes are discussed.

Growth and scintillation properties of Nd-doped Lu3Al5O12 single crystals by Czochralski and micro-pulling-down methods

“…The decay time profile was approximated by two exponential components and the decay time constants were 0.87 ms and 4.97 ms. The values are consistent with the m-PD grown one and the fast component and slow component are attributed to the host emission and a combination of the host and Nd 3 þ 4f-4f transitions [6,19,20].…”

Luminescence properties of Nd3+ doped LiLuF4 single crystals with different dopant concentrations

“…In fact, the materials, such as, CdWO 4 , Gd 2 O 2 S:Pr and Eu-doped sesquioxides are proposed for the X-ray radiology system. By previous our studies, trivalent rare-earth doped oxide scintillators like YAG:Nd, LuAG:Nd, LuAG:Tm, YAP:Tm and LuAG:Er found to demonstrate interesting properties including high light yield [1][2][3][4][5], intense emission bands in UV-IR region and enough decay time to detect by Si photodiode based detectors in X-ray CT system. Therefore, in this study, we focused attention on another type material, the Nd 3+ doped lutetium lithium fluoride (LuLiF 4 :Nd).…”

Optical and Near-Infrared Scintillation Properties of Nd3+-Doped YVO4 Crystals

“…Some researchers reported the NIR scintillation characteristics of various materials, such as oxides, halides, and metals. (5)(6)(7)(8)(9) Our group has recently studied some oxide laser materials activated with rare-earth ions, and they were found to show intense NIR 4f n -4f n emission peaks and good irradiation dose response under exciton with X-rays. (10)(11)(12)(13) Thus, the present study focuses on a Nd 3+ -doped yttrium vanadate YVO 4 crystal because it is one of the most efficient laser host crystals that provide 1064 nm light owing to the Nd 3+ ions.…”
