Webb30 mars 2024 · Abstract We report a new material, BaCN 2 :Eu 2+ for a very sensitive optical pressure sensor, 50 times more sensitive than ruby. Photoluminescence spectra of the BaCN 2 :Eu 2+ phosphor was measured under hydrostatic pressures from ambient pressure to 5.34 GPa at room temperature. Webb21 dec. 2024 · Photoluminescence provides readers with the appropriate background to thoroughly understand chemical literature involving photoluminescence measurements and interpret photoluminescence data from their own research.

In Fig. 1 we demonstrate that the ruby photoluminescent PL emission spectrum exactly matches the spectrum of hy-pothetical stimulated emission of defect states in Fig. 1 interpretation as “coherent stimulated emission” authorsb of the commented paper. WebbTime-resolved photoluminescence (TRPL) is a method where the sample is excited with a light pulse and then the decay in photoluminescence with respect to time is measured.

Webb1 juni 2024 · Ruby, Cr +3 -doped aluminium oxide (Cr:Al 2 O 3 ), is one of the most renowned laser materials. In the 1960s, ruby single crystal was used as the gain medium in the first-ever demonstration of solid-state stimulated laser emission [6]. This breakthrough paved the way for many new scientific and technological opportunities.
