Abstract

• Sensitized Mn 2+ luminescence is studied in lithium tetraborate. • Existence of complex luminescence centres is proposed. • Slow or ultrafast Mn 2+ luminescence decays occur depending on the excitation energy. • Mechanisms for excitation transfer and luminescence decay acceleration are proposed. Sub-nanosecond luminescence of Mn 2+ in Mn-, Sn/Mn-, and Cu/Mn-doped Li 2 B 4 O 7 ceramics is observed under laser excitation. Picosecond pulsed laser radiation (350–370 nm) generates the frequency-doubled radiation directly in a single microcrystal selected in a ceramic sample, with this secondary radiation falling within the impurity-induced VUV excitation bands of doped Li 2 B 4 O 7 . These excitation bands are attributed to the creation of an impurity-bound intra-anionic exciton in Me i O 4 –BO 3 –Mn Li complex centres (Me i = Mn, Sn, or Cu). The exciton, in turn, interacts with a nearby Mn 2+ ion due to mixing of the Mn 2+ excited states with the excitonic states. Exciton annihilation involves Mn 2+ energy levels as transient states and causes a sub-nanosecond radiative transition which is accelerated, being accompanied by rearrangement of the surrounding atoms. Excitation within the lower-energy bands is related to the other part of the complex luminescence centre, this is metal-to-ligand intra-anionic charge transfer, which makes an electron accessible to Mn Li , while the hole is transferred only during relaxation of the excited structure. Mn 2+ radiative transitions are not forced in the latter case, and slow Mn 2+ luminescence decay is observed.
