“…The glass ceramics containing Cr 3+ ion‐doped crystals such as spinel, 2 mullite, 3 and gahnite 4–6 and that containing Cr 4+ ion‐doped crystals 7–9 have been studied. However, the glass ceramics containing the ruby have never been reported.…”

We have developed the glass ceramics containing ruby crystals by heat treatment of a Cr3+‐doped SiO2–Al2O3–Y2O3 glass at 1550°C. The shape of precipitated crystals in the glass matrix was rod type whose average width and length were around 10 and 200 μm, respectively. From an X‐ray diffraction measurement and an electron probe X‐ray microanalysis, it was confirmed that the rod crystals were α‐Al2O3. Intense emission bands of Cr3+ at 694 nm, called the R‐lines, were observed in the glass ceramics heat treated above 1300°C. In addition, the intense red luminescence was observed only in the α‐Al2O3 rod crystals by a photoluminescence mapping image.

2014 Nous présentons les mécanismes de base de l'absorption d'un rayonnement de pompage et de l'émission de fluorescence des matériaux inorganiques luminescents et nous donnons la liste des principaux composés utilisés par la technologie moderne. Après avoir montré les relations entre les recherches conduites pour le développement des deux types de matériaux (luminophores polycristallins et monocristaux lasers) nous insistons plus sur l'état de l'art et les perspectives des recherches des luminophores pour l'éclairage, la télévision, les écrans renforçateurs de rayons X et les écrans électroluminescents. Abstract. 2014 We present the basic mechanisms of the absorption of the pumping radiation and the fluorescence emission of inorganic luminescent materials and we give the list of main compounds used by modern technology. Then, we show there were connections between polycrystalline phosphors and laser-material research. We insist on the present status and the future development of phosphors for fluorescent lighting, TV screens, X-ray intensifier screens and electroluminescent devices.

“…В работах [6][7][8] в качестве люминесцентного вещества были использованы органические красители, которые обладали хорошими характеристиками в плане преобразования солнечной энергии, но не были стабильны в долгосрочной перспективе. В связи с этим, начиная с 1970-х годов, стали активно развиваться люминесцентные солнечные концентраторы (ЛСК) на основе неорганических стекол с люминесцентными допантами: ионами редкоземельных элементов (РЗИ) [9][10][11][12] и ионами переходных металлов (в основном, хрома и марганца) [11,[13][14][15][16].…”

The work is devoted to the study of the spectral properties of potassium alumina-borate glass activated with different concentrations of trivalent chromium compounds. In this work, the glass transition temperatures of the composition (434°С) and the volume crystallization temperature of the glass matrix (600°С) were determined. Heat treatment of glass at the crystallization temperature led to the appearance of intense narrow luminescence bands in the region of 685–715 nm, which was associated with the nucleation of the crystalline LiAl7B4O17: Cr3 + phase in the glass matrix, in which chromium occupied positions in the high-symmetric octahedral environment. The concentration dependences of luminescence lifetime and quantum yield showed the presence of concentration quenching of the luminescence with an increase in the chromium content from 0.05 to 0.2 mol%. The maximum value of the quantum yield was 30%.
