Here we present a colloidal approach to synthesize bismuth chalcohalide nanocrystals (BiEX NCs, in which E=S, Se and X=Cl, Br, I). Our method yields orthorhombic elongated BiEX NCs, with BiSCl crystallizing in a previously unknown polymorph. The BiEX NCs display a composition‐dependent band gap spanning the visible spectral range and absorption coefficients exceeding 105 cm−1. The BiEX NCs show chemical stability at standard laboratory conditions and form colloidal inks in different solvents. These features enable the solution processing of the NCs into robust solid films yielding stable photoelectrochemical current densities under solar‐simulated irradiation. Overall, our versatile synthetic protocol may prove valuable in accessing colloidal metal chalcohalide nanomaterials at large and contributes to establish metal chalcohalides as a promising complement to metal chalcogenides and halides for applied nanotechnology.

We estimate an “augmented” measure of wealth incorporating social security wealth for the first time in Italy, and examine the composition and distribution of such augmented wealth among Italian households during the period 1991–2002. The path followed by augmented wealth from 1991 to 2002 is determined by two opposing forces: namely an increase in net worth and a decline in social security wealth, which appears to be much more pronounced in the first part of the period. Wealth inequality, after rising steeply at the beginning of the 1990s, leveled off during the second part of the period in question. The major contribution toward this upwards movement came from social security wealth, the distribution of which, although less unequal than that of real wealth and financial wealth, widened at a much faster pace at the beginning of the decade.
