摘要：
Although the Omega lambda intensity parameters and especially the Omega(2) parameter can show a considerable spread for a particular lanthanide ion in different host matrices, the values of these parameters for lanthanide ions in glasses are relatively close to each other. Combined with the fact that large errors are inherent to these parameters, we emphasize that one has to be careful when interpreting or comparing intensity parameters for lanthanide ions in glasses. The analysis of a large data-set of intensity parameters reported for glasses indicates that Omega(4) congruent to Omega(6). No correlation was found between the Omega(2) parameter and the two other parameters.
