Notes:
Y3Al5O12:Nd3+ nanoceramics were obtained by sintering nanocrystalline Y3Al5O12:Nd3+powders at 450 oC under different pressures between 2 and 8 GPa. The structural purity, residualstress, strain, texture, and crystallite size of the products were analysed with X-ray powderdiffraction. The results indicate that the average crystallite size remains unchanged at about 30 nmin spite of the heating and the pressure applied. No texture was observed. On the other hand, themicrostrains increase with increasing pressure, while the residual stresses are at their maximum inthe green body and the sample processed at 8 GPa. Increasing strains were observed to increase thewidth of the luminescence lines and to decrease the luminescence decay times
