“…31,32 Therefore, the luminescence behavior of Bi 3+ can be used as an indicator to evaluate the crystal structure of specific host compounds. Bi 3+ -doped Ba 2 Ga 2 GeO 7 , 33 Ca 3 Ga 4 O 9 , 34 Sr 3 Lu 2 Ge 3 O 12 , 35 and La 3 BWO 9 36 as promising phosphors for full-spectrum WLEDs have been developed. Moreover, the thermal behavior 37 and multimodal luminescence properties for X-ray detection and anti-counterfeiting of Bi 3+ combined with other activators 38 A series of Bi 3+ ion-activated Ba 1−x Sr x Ga 2 O 4 phosphors were explored in this work.…”

“…Generally, emitting centers and trapping centers are indispensably involved in an optical procedure, , where carriers are captured and released subsequently to combine with an activator under thermal disturbance or photostimulation. , Compared with the tervalent rare-earth metal ions with characteristic 4f transitions, Bi 3+ ions with an exposed 6s 2 energy level would be an effective activator since their emission strongly depends on the coordination and surrounding crystal field environment of the host lattice. , Therefore, the luminescence behavior of Bi 3+ can be used as an indicator to evaluate the crystal structure of specific host compounds. Bi 3+ -doped Ba 2 Ga 2 GeO 7 , Ca 3 Ga 4 O 9 , Sr 3 Lu 2 Ge 3 O 12 , and La 3 BWO 9 as promising phosphors for full-spectrum WLEDs have been developed. Moreover, the thermal behavior and multimodal luminescence properties for X-ray detection and anti-counterfeiting of Bi 3+ combined with other activators exhibit fascinating luminescence performance.…”

Ce3+/Tb3+‐coactived NaMgBO3 phosphors toward versatile applications in white LED, FED, and optical anti‐counterfeiting

“…52 Additionally, the deeper penetration depth (i.e., L) into the host body can also be responsible for the enhanced CL intensity. According to previously reported works, one knows that the L value can be calculated through using the empirical expression, as follows: 57,58 In these functions, A, ρ, E, and Z are the relative molecular mass, bulk density, accelerating voltage, and the atomic number or the number of electrons per molecule in the case compound, respectively. For the NaMgBO 3 :0.01Ce 3+ ,0.03Tb 3+ phosphors, the values of A (106.11 g/mol), ρ (2.93123 g/…”

Bismuth‐activated, narrow‐band, cyan garnet phosphor Ca3Y2Ge3O12:Bi3+ for near‐ultraviolet‐pumped white LED application

“…[6][7][8][9] To overcome this shortcoming, researchers have proposed a new strategy of mixing the near-ultraviolet (NUV)-LED chips with blue, green, and red phosphors to achieve the white light. [10][11][12][13][14][15] It can obtain not only a superior warm white light but also a higher excitation energy because of its NUV excitation. However, the traditional rare-earth ions (such as Ce 3+ or Eu 2+ ) activated phosphors, because of their 4f to 5d transition properties, usually show a strong A survey of the published literature shows that process modeling of CMCs has been studied by a number of researchers.…”
