Photoluminescence, thermal stability and structural properties of Eu3+, Dy3+ and Eu3+/Dy3+ doped apatite-type silicates

Photoluminescence enhancement of orange-emitting Ca5(PO4)2SiO4:Sm3+ phosphor through charge compensation of A+ (Li+, Na+ and K+) ions for white light-emitting diodes

“…need to be improved. [16][17][18][19] Therefore, it is important and necessary to explore orange/red-emitting phosphors with preferable luminescence performance. [20][21][22][23] The M 5 (XO 4 ) 3 Y (M = Ca, Sr, and Ba; X = P, V, As; Y = F − , Cl − , Br − , and OH − ) inorganic compounds with the apatite mineral structure always act as phosphor hosts on account of their great structural stability and low cost.…”

Excitation expansion in the high‐energy UV region for Dy3+‐doped medium‐temperature molten silicate glass phosphors

“…Luminescent materials with rare earth receive widespread attention for the applications in data storage, solid‐state lighting, photoelectric sensors, and medical imaging, where rare‐earth ions–doped glass phosphors have potential value in various fields 5–8 . Silicate glass can be low cost produced and has abundant raw materials, high mechanical strength, and superior chemical stability, making it an ideal matrix material for luminescence 9–13 . Moreover, if it can be molten at medium temperature while retaining excellent optical properties, it would be beneficial for energy conservation 14–16 …”

“…[5][6][7][8] Silicate glass can be low cost produced and has abundant raw materials, high mechanical strength, and superior chemical stability, making it an ideal matrix material for luminescence. [9][10][11][12][13] Moreover, if it can be molten at medium temperature while retaining excellent optical properties, it would be beneficial for energy conservation. [14][15][16] Among rare-earth ions, Dy 3+ with strong emission in the yellow and blue fluorescence regions due to 4 F 9/2 → 6 H 13/2 and 4 F 9/2 → 6 H 15/2 transitions emits a warm yellow-white light that has been extensively studied.…”

Influence of polyester fabric with infrared emissive additives on cell metabolism

“…Graphene is a well-known material which absorbs energy in a large wavelength range and emits IR radiation [14]. Apatites are also popular basements in composite materials, which can reflect and emit waves in the infrared range [18,19]. Iron oxide was included to the study as an antagonist to additives, being known as material with a high ability to absorb energy in the large wavelength range [20].…”
