Abstract
ABSTRACT We discuss the use of commercial high power light emitting diodes (LEDs) as a light source for fluorescence pressure measurements. The relatively broad light emitting spectra of single color LEDs (in comparison with lasers) do not prevent producing narrow fluorescence lines at least for two widely used pressure indicator materials, namely ruby ( ) and strontium tetraborate ( ). Strongest responses of both pressure gauges were detected for the green color LEDs with the average wavelength . LEDs might be easily implemented for producing fiber-coupled, as well as the parallel light sources. LEDs were found to be efficient to replace laser sources in piston-cylinder cell and diamond anvil cell fluorescence pressure measurement setups.

It provides an important forum for the presentation of experimental and theoretical advances in high pressure science in subjects such as:
condensed matter physics and chemistry
geophysics and planetary physics
synthesis of new materials
chemical kinetics under high pressure
industrial applications
shockwaves in condensed matter
instrumentation and techniques
the application of pressure to food / biomaterials
Theoretical papers of exceptionally high quality are also accepted.
