چکیده
The emission spectra (at T = 10 K and 296 K) and the excitation spectra (at T = 295 K) of zeolite-based luminophores of the types Zn:S i0 4:Mn and (C dO )2B2O vM n show the characteris tics of Mn2+ in tetrahedral and octahedral surroundings, respectively, as well as additional fea tures due to impurities and/or structural defects of the host crystal. The Z n S i0 4-type phosphor exhibits photostimulated emission, which can be assigned to trap states of the silicate host.

Dedicated to Professor A Ifred Klemm on the occasion of his 70th birthday In platelets of Cs2Zn3S4 with about 4% of the Zn substituted by Mn two nonequivalent centers of isolated Mn + were observed in addition to a broad EPR signal near g = 2 which is assigned to clusters of interconnected MnS4 units. The fine structure and hyperf ine structure parameters for the single-ion centers (all in unit...

The crystal structure of yeatmanite [MnsSb2]VI[Zn6Mn4(Si,.8Fe~:2)]IV028; PI, a = 5.443(3), b = 11.683(5), c = 9.134(4)A, 0< = 92.06(4), (3 = 101.19(4), 'Y = 76.34(4t, Z = I] from Franklin, New Jersey, has been refined to an R = 0.100 using 1881 reflections. The structure scheme proposed by Moore et al. [(1976); Neues Jahrb. Abh., 127, 47-61] was proved to be correct. The octahedral sheet consis...

متن کاملProtein phosphatase 2A inhibitors, I(1)(PP2A) and I(2)(PP2A), associate with and modify the substrate specificity of protein phosphatase 1.
Recombinant I(1)(PP2A) and I(2)(PP2A) did not affect the activity of the catalytic subunit of protein phosphatase 1 (PP1(C)) with (32)P-labeled myelin basic protein, histone H1, and phosphorylase when assayed in the absence of divalent cations. However, in the presence of Mn(2+), I(1)(PP2A) and I(2)(PP2A) stimulated PP1(C) activity by 15-20-fold with myelin basic protein and histone H1 but not ...
