Mechanochemical preparation of nanocrystalline metal halide phosphors

On the origins of the green luminescence in the “zero-dimensional perovskite” Cs4PbBr6: conclusive results from cathodoluminescence imaging

“…The luminescence (normalized) and absorption spectra of CsPbBr 3 (also prepared by ball-milling) are shown for comparison. 33 The luminescence spectra were excited at 410 nm. The absorption spectra were obtained by applying the Kubelka-Munk transformation to reflection spectra.…”

Preface

“…Some of these systems are highly exothermic, and mechanically induced chemical reactions are real fast, achieving total conversion to products within minutes. The next two papers describe the mechanochemical synthesis, characterization and properties of metal halide phosphors [28] and F ion conducting compositions in the LaF 3 /SrF 2 system [29]; the next three papers show that mechanical milling provides a very convenient route for fluorinating aluminum hydroxides [30], synthesizing a Ba-containing coordination polymer with a direct Ba-F bond [31] or to obtain fluorinated linkers for metal-organic frameworks, using liquid substrates and the Knoevenagel condensation reaction [32]. Papers dealing with different aspects of mechanochemistry in organic systems are next, including a solvent-free process for the nitration of toluene [33], the synthesis of polymer blends [34], functionalizing protein materials with luminescent dyes and anticancer drugs [35] and synthesizing metal (Ce) phosphonates including products which can be only reached using ball milling [36].…”
