“…The excitation spectra show the characteristic features of Eu 3+ excitation without any spectral shift in all samples under 613 nm emission. Swapna et al (2015) reported that among all excitations in Eu 3+ high intense emission peaks were observed at 364, 383, 395, 413, 467, 528, and 532 nm with the corresponding transitions being (Swapna et al, 2015). In the present study, the observed emission spectra of Eu 3+ showed excitation peaks at 391,412,436, and 452 nm (Figure 2 and 3).…”

Recent technological applications have generated more interest in the studies of different types of glasses. The wide applications of glasses take place due to their interesting properties such as low thermal expansion, high softening temperature, high resistance to chemical attack, high refractive index with low dispersion and mechanical strength. Eu 2 O 3 doped borate glasses were successfully synthesized by melt quenching method. The X-ray diffraction (XRD) spectra revealed that these glasses had amorphous nature. Optical properties of prepared samples were characterized by photoluminescence studies. The dielectric properties of glass samples were studied for different frequencies and different temperatures.

“…As matrizes luminescentes apresentam um valor de dopagem limite que resultará na maior intensidade da luminescência. De acordo com o material analisado é possível que esse limite seja relativamente baixo (menor ou igual a 1%), sendo que esse mesmo comportamento é observado para diversos sistemas presentes na literatura [8,9]. Emissão do espectro eletromagnético da matriz cerâmica com diferentes concentrações de íons terras-raras.…”

Resumo-Devido ao grande interesse da indústria eletrônica para novas aplicações ópticas, objetivou-se neste trabalho demonstrar o estudo da luminescência de conversão ascendente aplicado na matriz cerâmica MgTiO 3 dopada com óxído de érbio. A amostra foi excitada por uma fonte de diodo laser na região do infravermelho (980 nm). Obteve-se como resultado uma emissão na região do visível nas cores verde (525 a 575 nm) e vermelho (650 a 700 nm). Palavras-Chave-Luminescência de conversão ascendente, MgTiO 3 , Érbio, Óptica.

“…Rare-earth ions-doped luminescent materials have wide range of applications in which white light emitting diodes, solar cells, lasers, infrared to visible up-converters and optical communications. Oxide glasses are the most stable host matrices for practical applications due to their high chemical durability and thermal stability [1][2][3][4][5][6][7][8].Among these hosts, the borophosphate system is attractive due to its superior physical, structural and optical properties compared to pure phosphate or borate system [9][10][11][12][13].The low nonlinear dispersion of the highly rare-earth doped phosphate glasses enables their use in high power applications. Modification of phosphate glass with ZnO had improved glass durability while maintaining low glass transition temperature.…”

Zinc lithium lead calcium borophosphate glasses containing Er3+ in (40- x):P2O5:10ZnO:10Li2O:10PbO:10CaO:20B2O3:xEr2O3 (where x=1, 1.5,2 mol %) have been prepared by melt-quenching method. The amorphous nature of the glasses was confirmed by x-ray diffraction studies. Optical absorption, Excitation, fluorescence and Transmittance spectra were recorded at room temperature for all glass samples. Judd-Ofelt intensity parameters Ωλ (λ=2, 4, 6) are evaluated from the intensities of various absorption bands of optical absorption spectra. Using these intensity parameters various radiative properties like spontaneous emission probability, branching ratio, radiative life time and stimulated emission cross–section of various emission lines have been evaluated. Keywords: ZLLCBP Glasses, Optical Properties, Judd-OfeltTheory, Transmittance Properties.
