  Size-dependent properties of CdSe quantum dots

  摘要：

  Temperature dependences of the magnetic susceptibility X and heat capacity C-p of CdSe quantum dots with size d=2.8, 4.1, and 5.6 nm are compared to those of bulk CdSe to determine the size-dependent effects. With decreasing size d, the following effects are observed: (i) room temperature optical absorption shows a blueshift of the band gap; (ii) room temperature x-ray diffraction show wurtzite structure but with smaller lattice constants; (iii) magnetic susceptibility changes from negative (diamagnetic) for the bulk to positive X with magnitude increasing with decreasing d; and (iv) the Sommerfeld constant gamma determined from the C-p/T vs T-2 data increases. Possible explanations for these size-dependent properties are presented.

  phospho在离子基离子液体中的溶解行为和硒的活化

  摘要：

  通过31 P和77 Se核磁共振（NMR）实验首次研究了灰色硒在phospho基离子液体（ILs）中的溶解行为。研究证明形成了三烷基膦硒化物，该三烷基膦硒化物可以在随后形成的金属硒化物中用作硒的储库。

  日期：——

  The dissolution behaviour of grey selenium in phosphonium based ionic liquids (ILs) has been investigated for the first time by 31P and 77Se nuclear magnetic resonance (NMR) experiments. The investigations evidence the formation of trialkylphosphane selenides which can serve as a selenium reservoir in the subsequent formation of metal selenides.
