The structure and luminescence properties of green Ca3Al2O6:Bi3+ phosphors

Design of a defect‐induced orange persistent luminescence phosphor BaZnGeO4:Bi3+

“…Combining the analysis of PL spectra and the comparison of PL spectra of BZGO:Bi 3+ and BZGO host, one can speculate that the two emission bands centered at 440 nm and 595 nm of BZGO:Bi 3+ can be attributed to different Bi 3+ emitting centers. 23 And together with the results of XRD, XPS measurements, and PL spectra, it can be concluded that Bi 3+ ions were incorporated into the host lattice successfully.…”

Unravelling the energy transfer mechanism in bismuth co-activation of LaInO3:Sm3+/Ho3+ nanophosphor for color-tunable luminescence

“…[30][31][32][33][34][35][36][37][38] The emission spectrum of Bi 3+ contains a broad band, whose peak maximum varies from blue to green for different host lattices 39 because the outer 6s 2 electronic congurations of Bi 3+ depend strongly on their environmental conditions, such as covalence, coordination number and site symmetry. [40][41][42] Among the RE ions, Sm 3+ and Ho 3+ are important activators for producing signicant orange-red and green emissions for wide applications in optical displays, remote sensing and medical purposes. 43,44 However, it is quite a challenge to select a proper host because doping and co-doping inuence the optical properties of luminescence materials.…”

White luminescence and energy transfer process in Bi3+,Sm3+ co-doped Ca3Al2O6 phosphors

“…1 S 0 transition [22,23]. Its color varies from ultraviolet to blue and even green in appropriate hosts because that the outer 6s 2 electronic configurations of Bi 3+ depend strongly on their environmental conditions, such as covalence, coordination number and site symmetry [24][25][26]. ET process from Bi 3+ to RE ions may occur due to the overlap of emission of Bi 3+ and excitation of RE ions.…”
