求翻译：结果表明：La3+的掺入量越高上转换效率越高，Yb3+、Er3+的掺入量影响相对小得多，而且烧成温度也存在着峰值，只有接近此温度时上转换效率才高。是什么意思？

The results showed that: the higher the conversion efficiency higher la3 + incorporation yb3 + + er3 incorporation of a much smaller, and the firing temperature there are also peak, only close to the temperature on conversion efficiency.

Results show that the 3+ La mixing on the greater the amount, the higher conversion efficiency Yb Er 3+, 3+ of the Mixed impact of the relatively small pots, and much more are also there is a peak temperature, the temperature is only about the conversion efficiency is high.

The result indicated that,La3+ mixes in the quantity to be higher on the transfer efficiency to be higher, Yb3+, Er3+ mix in the quantity influence relatively to be much smaller, moreover fires the temperature also to have the peak value, when approaches this temperature on the transfer efficiency i

Results show that La3+ added on the amount, the higher conversion efficiency, the higher, Yb3+, and Er3+ are much mixed into relatively small, there is a peak and the firing temperature is only when close to this temperature conversion efficiency is high.
