Study on the sensitization of Gd3+ on Ce3+/Tb3+ co-doped GBS scintillating glass

Gd3+-doped sol-gel silica glass for remote ionizing radiation dosimetry

“…In fact, due to the optical activity in the UV domain, the incorporation of Gd 3+ ions inside oxide glasses leads to efficient scintillator and phosphor materials [10,11]. However, in most of the investigated glasses, the Gd 3+ ions have mainly been used as sensitizers for other rare-earth ions to enhance their luminescence [12][13][14][15][16]. This mostly concerned multicomponent glasses, which contain glass modifier elements, such as aluminum, that could decrease the glass resistance to radiations [17].…”

Sensitization Mechanism of Alumina Aerogels: Introducing Gd3+ as a Sensitizing Ion to Enhance the Luminescence Intensity of Tb3+

“…[12][13][14] The introduction of Gd 3 + and Ce 3 + ions have a significant effect on enhancing the luminous intensity of Tb 3 + . [15][16][17] In addition, since the phosphor is composed of matrix and fluorescent activating ions, [18][19][20] the choice of the matrix is also another key factor for the production of highefficiency green phosphors. Hence, the matrix should have good physical and chemical stability and light transmittance.…”

“…In order to enhance the luminous intensity of green phosphor, some sensitized ions, such as Ce 3+ , Eu 3+ and Gd 3+ , are usually doped into the phosphor containing Tb 3+ ions [12–14] . The introduction of Gd 3+ and Ce 3+ ions have a significant effect on enhancing the luminous intensity of Tb 3+ [15–17] . In addition, since the phosphor is composed of matrix and fluorescent activating ions, [18–20] the choice of the matrix is also another key factor for the production of high‐efficiency green phosphors.…”

Photoluminescence and scintillation properties of Ti-doped CaHfO3 crystals

“…Because no scintillator can fulfill all of the requirements above, users select suitable scintillators for each application, and many kinds of scintillators have been developed. [9][10][11][12][13][14][15][16] Recently, hafnium oxides have been synthesized as candidates for scintillators because their high ρ is attractive. [17][18][19] CaHfO 3 has a high ρ (6.9 g cm −3 ) and a high Z eff (65.2).…”
