“…Alternatively, Bi-doped glass ceramics can be prepared, that is, glass-crystal composites, which are formed by the controlled crystallization of a precursor glass during a secondary heat-treatment process. [29][30][31] This path relies on internal nucleation, crystallization of the desired phase (with low phonon energy), and incorporation of the optically active Bi species into the crystal phase. So far, success on this path has been very limited.…”

Tuning the optical properties of active species embedded within a glass matrix by modifying the ligand environment is of interest for luminescence-based technologies, for example, in optical sensing, data transmission, or spectral conversion. Here, we discuss a facile synthesis procedure for a glass-crystal composite material comprising of bismuth (Bi)-doped zirconia within an aluminoborate glass phase. The approach offers tunable and broad photoemission characteristics in the visible spectral region from 400 to 750 nm. Incorporation of Bi ions into the crystal phase enhances the photoemission intensity by two orders of magnitude, with an external quantum efficiency of about 29%. At higher ZrO 2 dopant concentration, we observe a red-shift of both the excitation and the emission bands to match commodity ultra-violet light emitting diodes as excitation sources. Encapsulation within the aluminoborate glass phase provides advantageous thermal behavior, with the emission intensity remaining at >80 % of its initial value up to a temperature of 400 K.

“…It is well‐known that glass‐ceramics can hybridize glass and crystal, and it usually exhibits better optical properties than either glass or crystal . This motivates us to start the project on bismuth‐doped glass‐ceramics . It is our wish to find such a hybrid system which can stabilize bismuth to the valence state active for NIR emission, and at the same time can enhance the bismuth luminescence.…”

Bismuth‐doped glasses and crystals have been widely investigated due to their intriguing potential applications in superbroadband fiber amplifier and lasers in new NIR spectral range. However, few reports have been devoted so far to bismuth‐doped transparent glass‐ceramics. Here, this work reports on bismuth‐doped silicate glasses and glass‐ceramics, which were prepared by melt‐quenching and consequent annealing processes, respectively. On the basis of the analyses on crystallization kinetics, nucleation and growth rate of crystalline phase can be modulated and Sr2YbF7 nanophase can, therefore, be precipitated uniformly inside the glass matrix in a controlled way to maintain proper transparence especially in optical telecommunication windows. Once the nanophase comes into being, enhanced bismuth NIR luminescence can be observed by more than 40 times upon excitation of 470 nm. Similar enhancement can appear upon different excitation schemes and the mechanism is discussed accordingly. Such Bi doped transparent glass‐ceramics with improved luminescence efficiency might find application in fiber lasers for future optical fiber communication.

Bi-doped MO-B 2 O 3 (M=Ca, Sr, Ba) glasses were prepared by melting method. Excitation spectra, visible and infrared luminescence spectra were measured. Near infrared (NIR) emissions located at about 1190 nm with FWHM only 40 nm and at 1300 nm with FWHM about 200 nm can be observed in different samples when excited by 808 nm LD excitation. The two emission bands have different excitation bands. Red emission centered at 660 nm related to Bi 2+ can be observed in some samples. The NIR emission at 1300 nm band disappears with the increase of optical basicity, while that of the NIR emission at 1190 nm band shows a contrary tendency. We proposed that the NIR emissions located at 1190 nm and 1300 nm originated from different bismuth centers. The infrared emission peak at about 1300 nm derives from low valence Bi ions according to the Duffy's theory of optical basicity.
