Saros Körfezi̇ Ki̇l Örneği̇ni̇n Yapisal Karakteri̇zasyonu, Termo Ve X-Işini İle Uyartmali Lumi̇nesans Özelli̇kleri̇ni̇n İncelenmesi̇

“…Energy levels corresponding to wavelengths are shown. In addition, the CIE diagram given next to this graph shows the point where the RL spectrum of clay in the visible region coincides on the color scale[16,17]. It can be understood that clay exposed to X-ray emits an orange, close to red, emission.…”

Luminescence performance and energy transfer mechanism investigation of RE3+ (Eu3+/Tb3+/Ce3+)-doped Y2O3 phosphors

“…Y 2 O 3 has stable physical and chemical properties, and researchers have prepared various Y 2 O 3 -based phosphors. 13–16 For example, Y. Kumar et al prepared Y 2 O 3 :Eu 3+ phosphor by coprecipitation method, and studied its structure and optical properties in detail. 17 R. E. Muenchausen et al synthesized Y 2 O 3 :Tb 3+ phosphors and investigated the effect of Tb 3+ doping on the photoluminescence performance of Y 2 O 3 :Tb 3+ .…”

Structural and tunable optical properties of LiMgPO4:Tb3+ phosphor fabricated by sol–gel method

“…One area of particular importance is the development of luminescent materials doped with trivalent rare earth metals (RE: Eu 3+ , Dy 3+ , Tb 3+ , etc.). These materials have found versatile applications in various fields, including electroluminescent and screen technology, lasers, W‐LEDs, biomedical diagnosis applications, fluorescent technology, laser spectroscopy, optical storage systems, and optical fiber amplifiers, which show rapid and remarkable progress in this area 1–13 . Typically, when incorporated into various host matrices, the trivalent terbium (Tb 3+ ) ion exhibits green emission when excited by different radiation sources like ultraviolet (UV) and X‐rays 14–18 .…”

“…These materials have found versatile applications in various fields, including electroluminescent and screen technology, lasers, W-LEDs, biomedical diagnosis applications, fluorescent technology, laser spectroscopy, optical storage systems, and optical fiber amplifiers, which show rapid and remarkable progress in this area. [1][2][3][4][5][6][7][8][9][10][11][12][13] Typically, when incorporated into various host matrices, the trivalent terbium (Tb 3+ ) ion exhibits green emission when excited by different radiation sources like ultraviolet (UV) and X-rays. [14][15][16][17][18] The green emissions in Tb 3+ -doped phosphors originate from transitions between the 5 D 4 and 7 F J states (J = 0-6).…”
