Laser Wavelength Selection In Raman

Laser wavelength selection, a critical determinant of accuracy and data quality, is guided by factors such as resonance, fluorescence, and sample absorption. Ensuring the correct laser wavelength leads to optimal excitation and signal strength, facilitating precise and informative analysis. Luminous evolution In the early days of Raman spectroscopy, light sources like arc lamps and incan... » read more

FTIR On Earth, Mercury In Focus

On early hours on 19th October 2018 at Guiana Space Centre in Kourou in French Guiana an Ariane 5 rocket successfully launched the BepiColombo mission. It started its 7 years journey to Mercury. The joined mission of the European Space Agency (ESA) and the Japan Aerospace Exploration Agency (JAXA) was named in honor of Giuseppe “Bepi” Colombo, an Italian scientist who studied Mercury and fi... » read more

Empowering Universities By Retaining Raman Knowledge

A big chunk of precious research funds spent on an expensive piece of equipment, for example a Raman microscope. Now, such a magnificent piece of hardware can seem quite intimidating. After all, it could be capable of building a spaceship! Now a poor graduate student must face copious amounts of training, becoming a real expert over the span of 3 to 4 years. Mostly because the professor ... » read more

Tiny Dots, Big Impact: The Luminous World of Quantum Dots

In the early ’80s, Alexey Ekimov and Louis E. Brus independently researched semiconductor clusters, leading to the discovery of quantum dots (QDs). QDs are nanoscale semiconductor particles with unique optical and electronic properties. In 1993, Moungi Bawendi improved quantum dot production, making them nearly perfect for various applications. By the late ’90s and early 2000s, quantum d... » read more

Particle Filter Material Choice For Raman And FTIR Microscopy

The filter material to analyze particulate matter with Raman or FTIR microspectroscopy plays a vital role. Their simple task is to filter liquids to isolate solids onto filters – but as soon as you introduce spectroscopic methods, the requirements on the filter increase drastically. But let’s start at the beginning: Which filters are at our disposal, and how do we select the right one for... » read more
