Rb Cd F 3 : Mn 2 + : A potential ultraviolet dosimeter material

Abstract

Optical absorption and optically stimulated luminescence measurements have been made on RbCdF3:Mn2+. We show that there is an ultraviolet (UV) response that covers the UV spectrum and hence this compound is applicable for passive UV detection and dosimetry. There is a fast UV-A and UV-B stimulated luminescence decay when compared with the bleaching of the deep UV induced optical absorption that can be explained in terms of a distribution of carrier traps with different detrapping rates.

Structural, electronic, magnetic and elastic properties of xenon-based fluoroperovskites XeMF3 (M = Ti, V, Zr, Nb) via DFT studies

“…They have received attention in the elds of scintillation materials, optical lithography and radiation dosimeters, as well as in the semiconductor industry. [1][2][3] Various applications in these elds have made SrLiF 3 , RbCaF 3 , KCaF 3 , BaLiF 3 and other materials of this class of great interest, but to explore the physical properties of this class, theoretical and experimental investigation is required.…”

Spectral tuning of colloidal Si nanocrystal luminescence by post-laser irradiation in liquid

“…Semiconductors with optical response in the ultraviolet (UV) region have evoked immense interest from researchers owing to various potential applications, such as light-emitting diodes, photodetectors, and nanomedicine (bioimaging). [1][2][3][4][5][6][7] Specically, UV light emission from semiconductors can be utilized for applications in high-density information storage devices (i.e., the shorter wavelength a light-emitting device operates, the more information the device can store) because the focus of UV light is more sharp than the longer wavelength light due to the diffraction limit. Moreover, because the UV light tends to produce lower heat radiation than the near-IR light, UV lightemitting devices are also suitable for medical care of heatlabile areas in the human body such as surgical procedures to correct nearsightedness.…”

Radiation‐induced optically stimulated luminescence in Mn2+ and Eu2+ doped RbMgF3

“…1 Introduction Fluoroperovskites (ternary fluorides crystallizing in a perovskite structure) are known to display optically stimulated luminescence (OSL) after exposure to ionizing [1][2][3][4][5] or non-ionizing radiation [6], which makes them good candidates for dosimetry applications [5]. We have recently shown that OSL can be observed in RbMgF 3 :Mn 2+ and reported thermoluminescence (TL) in polycrystalline samples [4].…”
