Table of contents of the journal Annalen der Physik for the issue of June 1905. Einstein's paper on the photoelectric effect is sixth on this list. The article "Über einen die Erzeugung und Verwandlung des Lichtes betreffenden heuristischen Gesichtspunkt" ("On a Heuristic Viewpoint Concerning the Production and Transformation of Light") [einstein 1] received 18 March and published 9 June ...
In 1905, Albert Einstein published a paper advancing the hypothesis that light energy is carried in discrete quantized packets to explain experimental data from the photoelectric effect. Einstein theorized that the energy in each quantum of light was equal to the frequency of light multiplied by a constant, later called the Planck constant. A ...
Photoemission electron microscopy (PEEM, also called photoelectron microscopy, PEM) is a type of electron microscopy that utilizes local variations in electron emission to generate image contrast. [ citation needed ] The excitation is usually produced by ultraviolet light , synchrotron radiation or X-ray sources.

Einstein's paper on the photoelectric effect is sixth on this list. The following chronology of Einstein's scientific discoveries provides a context for the publications listed below, and clarifies the major themes running through his work. Einstein's scientific career can be broadly divided into to periods.
English: Diagram of the photoelectric effect with zinc (Zn) x: frequency of light; y: kinetic energy of the electrons With the spectrum of visible light the electrons aren't emitted.
To explain the photoelectric effect, Albert Einstein assumed heuristically in 1905 that an electromagnetic field consists of particles of energy of amount hν, where h is the Planck constant and ν is the wave frequency.
English: The photoelectron emitter (E) and collector (C) electrodes are placed in an evacuated quartz tube. When ultraviolet light hits the surface of the emitter, the ejected electrons are prevented from reaching the collector by a sufficiently high negative voltage, or helped to reach the collector by a positive voltage.
