Effect of Nd concentration on structural and optical properties of Nd:Y2O3 transparent ceramic

Spectroscopic analysis on the basis Judd–Ofelt theory of Nd 3+ in (Y 0.985 Nd 0.015 ) 2 O 3 : A transparent laser-host ceramic

“…Although high melting temperature (2430 C) and presence of structural phase transitions at 2280 C make it difficult to grow large size and high-quality Nd:Y 2 O 3 single crystals [5,6], it is relatively easy to fabricate Nd:Y 2 O 3 in ceramics form below 2000 C. Ceramics also offer their advantage of allowing higher Nd doping concentration without compromising on the transparency. Though, several research groups have reported the lasing efficiency, emission spectra and the stimulated emission cross section of transparent Nd:Y 2 O 3 and YAG ceramic [7][8][9][10][11][12][13][14][15][16][17], most of these investigations are on 1.0 atm% Nd 3+ doped ceramic because a doping of typically 1 mol% was considered optimum for high performance laser application. The higher doping concentration is expected to reduce the emission lifetime of the luminescent Nd 3+ ions and thus the laser efficiency, due to concentration quenching effects [15,16].…”

Thermoluminescence of sol–gel derived Y2O3:Nd3+ nanophosphor exposed to 100MeV Si8+ ions and gamma rays

“…No additional peaks and no change in peak position from the doped samples were detected. Also, no significant change in the XRD pattern was observed due to the incorporation of Nd 3+ probably due to close ionic radii of Y 3+ (0.90 Å) and Nd 3+ (0.98 Å) [30].…”

Fabrication of Transparent Yttria Ceramics by Spark Plasma Sintering

“…Transparent polycrystalline yttria ceramics provides high potentials for optical applications, such as solidstate lasers [1][2][3], host materials for scintillators [4], missile domes [5] and light bulb envelopes [6] due to its high melting temperature around 2430…”
