Описание: This book reviews the application of semiconductor nanocrystals also known as colloidal quantum dots (QDs) to LED lighting for indoors and outdoors as well as LED backlighting in displays, summarizing the color science of QDs for lighting and displays and presenting recent developments in QD-integrated LEDs and display research. By employing QDs in color-conversion LEDs, it is possible to simultaneously accomplish successful color rendition of the illuminated objects and a good spectral overlap between the emission spectrum of the light source and the sensitivity of the human eye at a warm white color temperature – something that is fundamentally challenging to achieve with conventional sources, such as incandescent and fluorescent lamps, and phosphor-based LEDs.

Описание: Nanocrystals and Their Mesoscopic Organization is an up-to-date monograph on an important aspect of nanoscience and technology. It opens with an elegant introduction including a brief historical account. Emphasis is then given to diverse synthetic methods, both chemical and physical, in addition to modern hybrid methods. The orientation shifts gradually to properties of nanocrystals that evolve with size; detailed discussions are to be found on mesoscalar assemblies in different dimensions, special cases of core-shell and magic nuclearity nanocrystals. The authors also address applications of nanocrystals, carefully separating out potential applications and those that have already emerged, and cite around 900 references from the literature, most from the last decade. Tables providing information at a glance and schematic diagrams at relevant places, make the monograph appealing to read. Occasionally, the reader is reminded of the contributions of celebrated past masters such as Michael Faraday. In summary, the monograph serves as a general introduction as well as a handy reference for the entire community of researchers and practitioners.

Описание:
Melt quenching--the method of quenching from the liquid state--provides new opportunities for producing advanced materials with a unique combination of properties. In the process of melt quenching, attainment of critical cooling rates can produce specific structural states of the material. Nanocrystalline materials produced by melt quenching are classified as nanomaterials not only by their nanoscale structural elements but also by the effects these elements have on the properties of the material.
The result of 30 years of research, Melt-Quenched Nanocrystals presents a detailed and systematic analysis of the nanostructured state formed in the process of melt quenching and subsequent thermal and deformation effects. It covers the metallurgical and mechanical properties of nanomaterials, focusing particularly on properties derived from nanocrystals and their agglomeration. The text introduces four different types of nanocrystals that can be produced by melt quenching, each having different structures and properties:
Type I nanocrystals formed when crystallization takes place completely during melt quenching
Type II nanocrystals formed when melt quenching is accompanied by amorphous state formation along with partial or complete crystallization
Type III nanocrystals formed when melt quenching results in the formation of the amorphous state, and nanocrystals can be produced as a result of the subsequent thermal effect
Type IV nanocrystals formed when melt quenching leads to the formation of the amorphous state, and nanocrystals can be produced as a result of the subsequent deformation effect
The possible uses for these materials are extensive, with applications from coatings to biological compatibility. The final section of the book presents a discussion of existing and future applications of nanocrystals produced by different melt-quenc
