前驱溶液的pH值对Y2O3:Eu3+荧光粉发光性质的影响
Influence of acidity on properties of combustion-derived Y2O3:Eu3+ phosphors
摘要
Abstract
Y2O3:Eu3+(3%)nano powders were prepared by auto-combustion method and the effect of pH value of the precursor solution was investigated. The XRD and SEM analyses indicate that ssmples prepared under high pHvalue have less porous morphology and larger particle size, at the same time, they present stronger luminescence intensity revealed by emission. The excitatin spectra show that the decay curves show shorter lifetime with the increase of crystalline size.关键词
