High pressure luminescence and time resolved spectra of La$_2$Be$_2$O$_5$:Pr$^{3+}$

S. Mahlik , Michał Malinowski , M Grinberg


We present luminescence, luminescence excitation and luminescence time resolved spectra of La2Be2O5:Pr3+ system. We used high pressure spectroscopy approaches, with high pressure applied in diamond anvil cell (DAC) and sapphire anvil cell (SAC), for detailed analysis of luminescence related to the 4f5d → 4f2 and 4f2 → 4f2 transitions. We present effect of up-converted luminescence related to 4f5d → 4f2 transition excited with 488 nm. We also discussed possibility of existence of praseodymium trapped exciton (PTE) states in La2Be2O5:Pr3+ system. Lack of the PTE is attributed to high quantity of bulk modulus of this material.
