The first X-ray Image of a Single Atom
X-ray cystallography is a popular technique for determining crystal atomic structure. However, rather than imaging individual atoms directly, this technique relies on the scattering of…

A 3D Printer can be used to create Carbon Dioxide Filters
3D printing, also known as additive manufacturing, is a technique for producing three-dimensional objects by depositing successive layers of material. While the effectiveness of the…
Solid-state Physics
The study of rigid matter, or solids, using methods such as quantum mechanics, crystallography, electromagnetism, and metallurgy is known as solid-state physics. It is a…
Superluminescent Diode
A superluminescent diode (SLED or SLD) is a superluminescent edge-emitting semiconductor light source. SLD is a semiconductor light source that emits broad-spectrum light with a…
Laser Diode
A laser diode (LD) is a semiconductor device similar to a light-emitting diode in which a diode pumped directly with electrical current can create lasing…
Photovoltaic Effect
The photovoltaic effect occurs when a material generates voltage and electric current when exposed to light. It is both a physical and chemical occurrence. It…
Optical Physics
Optical physics is the study of the generation of electromagnetic radiation, its properties, and its interaction with matter, particularly its manipulation and control. It is…
Measurement of Power Levels One Trillion Times Lower Than Usual by Quantum Scientists
A nanodevice created by Finnish researchers can detect microwave radiation’s absolute power down to the femtowatt level at extremely low temperatures, a scale a trillion…
Phosphoroscope
A phosphoroscope is a piece of experimental equipment invented by physicist A. E. Becquerel in 1857 to measure how long it takes a phosphorescent material…
Phosphorescence
Phosphorescence, like fluorescence, is a type of photoluminescence. When exposed to shorter wavelength light (radiation), a phosphorescent substance will glow, absorbing the light and reemitting…
Luminescence
According to the IUPAC definition, Luminescence is the “spontaneous emission of radiation from an electronically excited species (or from a vibrationally excited species) that is…
Photoluminescence
Photoluminescence is a phenomenon in which a material emits light after absorbing photons. It is a type of luminescence, which refers to the emission of…
