Optical excitations in electron microscopy
TL;DR: In this paper, a quantum-mechanical description of the interaction between the electrons and the sample is discussed, followed by a powerful classical dielectric approach that can be in practice applied to more complex systems.

TL;DR: In this paper, a survey is given of recent results concerning particle-size dependences of the optical plasma resonance absorption and of the FIR absorption of small noble metal particles, and it is shown that the spectra are strongly changed if the particles of a sample interact with each other.
Journal ArticleDOI
Electronic properties of small metallic particles
TL;DR: In this paper, the quantum size effects in small particles are analyzed theoretically from the point of view of the statistics of discrete energy levels, and the existing experimental results are discussed, where the critical fields in small metallic particles, the magnetic field dependence of their microscopic properties, and fluctuations in small superconductors are discussed.

Elementary excitations in solids
TL;DR: In this article, the authors describe the behavior of simple metals, rather than the complicated metals, such as the transition metals and the rare earths, and discuss the applications of such simple metals.

The limitation of electron mean free path in small silver particles
U. Kreibig,C. v. Fragstein +1 more
TL;DR: In this article, absorption measurements of spherical silver particles suspended as colloid in photosensitive glasses were performed and it was shown that the absorption coefficient at the wavelength of absorption peak (λ = 0.405 μ) remains constant, whereas the refractive index increases by about a factor of 5 when the particle size decreases.

Electronic properties of small silver particles: the optical constants and their temperature dependence
TL;DR: In this article, the optical plasma resonance absorption of small silver particles embedded in glass has been investigated, and it has been shown that normal metallic properties are present in silver particles which contain more than about 400 atoms.

Optical Properties of Small Gold Particles
TL;DR: In this paper, the optical absorption of dispersions of gold particles is studied as a function of particle size, temperature, and method of preparation, and the absorption spectra for gold sols in glass and water with small spread in particle size are compared to spectra calculated from Mie theory and the most reliable of recently measured optical constants of gold.

Dielectric function and plasma resonances of small metal particles
TL;DR: Using the simple model of electrons in a box, a dielectric function is derived which should be appropriate for small metal particles as mentioned in this paper. But the model is not suitable for all metal particles.
