STRONTIUM BORATE

BeschreibungStrontium tetraborate, SrB4O7, (SBO) has been investigated as a potential nonlinear optical material with excellent mechanical and optical properties such as a high power second harmonic generation (SHG) coefficient, high optical damage threshold, high hardness, etc. Additionally, the SBO crystals possess high UV transmittance at wavelengths down to about 130 nm. SrB4O7 congruently melts at 994 °C.

VerwendenStrontium tetraborate is transparent across the far UV to far infra-red spectrum. Thus, it has great potential for use as lens components in optical devices such as those used for the fabrication of very large scale integrated circuits by a lithographic technique. A number of phosphors based upon the matrix, SrB4O7, have been investigated. Strontium tetraborate when activated by Eu2+, is used as a phosphor in “black-light” lamps for tanning salons.
