Tunable thermochromic properties of V 2 O 5 coatings

Optical and morphological properties of thermochromic V2O5 coatings

We present optical and morphological characterizations performed on thermochromic V2O5 coatings. V2O5 coatings were obtained by oxidation of as-deposited VOx films. Comparisons were made among coatings oxidized at various temperatures. Photographic evidence is also shown to provide the reader a clear visual description of the color change that occurs during thermochromic process. Detailed study...

7 O ct 2 00 5 Electronic Properties of α ′ - NaV 2 O 5

Luminescence of CS 3 V 2 O 4 F 5

The luminescence of complex ions like vanadate, niobate and tungstate is well known and has been studied intensively [1]. We have shown that edgeor face-sharing octahedra of this type are luminescent species with high quenching temperatures [2,3]. Examples are Mg4Nb20g and BasSrNb209 with Nb20g8_ anions and Ba3W20g with W2O96anions. These anions consist of face-sharing niobate and tungstate oct...

Electronic Properties of α ′ - NaV 2 O 5

1 General properties of α −NaV 2 O 5 and motivation for a spectroscopic study Introduction – α −NaV 2 O 5 is one of the several phases in the class of Na x V 2 O 5 systems [1] and until now it is by far the most studied of them. Since 1996 this compound (denoted in the following simply by NaV 2 O 5) has received considerable attention because it was thought to be the second realization, after C...

v 2 3 0 O ct 2 00 5 Complex Network Properties of Chinese Natural Science Basic Research

In this paper, we studied the research areas of Chinese natural science basic research from a point view of complex network. Two research areas are considered to be connected if they appear in one fund proposal. The explicit network of such connections using data from 1999 to 2004 is constructed. The analysis of the real data shows that the degree distribution of the research areas network (RAN...
