Spectroscopic properties of Bi2ZnOB2O6 single crystals doped with Pr3+ ions: Absorption and luminescence investigations

Correlations between Oxygen Uptake and Vacancy Concentration in Pr-Doped CeO2

“…In addition, a strong absorption is observed between 400 and 650 nm for the Pr–CeO 2 materials because of Pr 3+ transitions. In the work by Kasprowicz et al on Pr-doped Bi 2 ZnOB 2 O 6 , Pr 3+ absorption bands between 430 and 490 nm were attributed to 3 H 4 ground state to 3 P J transitions and those between 560 and 610 nm from 3 H 4 to 1 D 2 transitions. Also, in the work by Strzęp et al, a prominent 488 nm 4f–4f band was assigned to 3 H 4 transitions to 3 P 0 multiplets.…”

Bifunctional Bi2ZnOB2O6:Nd3+ Single Crystal for Near Infrared Lasers: Luminescence and μ-Raman Investigations

“…Low-intensive bands in NIR range located at about 2373 nm correspond to transition from the 4 I 9/2 ground state to the 4 I 13/2 excited state. Moreover, the ultraviolet cutoff absorption edge of the BZBO:Nd 3+ crystals is observed at about 350 nm, and in the spectral region below 350 nm the Nd 3+ absorption is overlapping with strong host absorption …”

“…Recently RE doped BZBO crystals were intensively studied because of their promising optical properties and consequently numerous potential applications. Moreover, BZBO materials in the form of single crystals, glasses, as well as powders − may be efficiently doped with RE ions resulting in effective luminescence in visible (VIS) and/or NIR spectral range. The structure and some of vibrational properties of pure and Pr 3+ doped BZBO single crystal were previously reported by us .…”

A new melilite-type rare-earth borate CdTbGaB2O7 and multicolor tunable emission in the CdTb1−xSmxGaB2O7 (0 ≤ x ≤ 0.2) phosphors

“…[10][11][12] When active laser medium (such as Er 3+ , Nd 3+ or Pr 3+ ions) are doped into this crystal structure, the obtained crystals may show both luminescence and NLO properties, which makes them very attractive for the new generation of laser frequency converters, the representative crystals including Bi 2 ZnOB 2 O 6 :-Yb 3+ /Er 3+ , Bi 2 ZnOB 2 O 6 :Nd 3+ and Bi 2 ZnOB 2 O 6 :Pr 3+ . [13][14][15] In addition, not long ago, two new melilite-type borogermanates, Ca 2 GeB 2 O 7 and Ca 1.78 Cd 0.22 GeB 2 O 7 , were also reported, among which Ca 2 GeB 2 O 7 has a short UV cutoff edge (<200 nm), indicating its potential as an optical material in the UV or DUV region. 16 The compounds mentioned above are the only borates with melilite structure reported so far.…”
