The chemical formula of the phosphor is SrMoO4:Eu. The method comprises the following concrete steps that: according to the molar ratio of 2:100:100 to 4:100:100, Eu2O3, MoO3 and SrCO3 solids are put into a mortar to be ground and fully mixed; an obtained product is placed in a crucible in a muffle furnace to be roasted for 3 to 4 hours at the temperature between 500 and 700 DEG C, and then a needed product can be obtained.

该荧光粉的化学式为：SrMoO 4 ：Eu 3 ，具体步骤为：将Eu 2 O 3 ，MoO 3 和SrCO 3 固体按照摩尔比为2∶100∶100～4∶100∶100的比例置于研钵中研磨，使其充分混合；将所得产物置于坩埚内放在马弗炉中于500℃～700℃的温度下焙烧3-4h，即得所需产品。

The tungsten melting pot is used in SL63-7BL vacuum resistance furnace, and tantalum plate is used to gathering bulk,raw terbium metal is purified by distillation at the temperature of 1 750~1 800℃ with the vacuity of 5×10-3Pa.

在SL63—7BL真空电阻炉中使用钨坩埚，钽片做收集筒，在真空度为10-3Pa和1750￣1800℃温度下蒸馏提纯金属铽，工艺可靠，可以批量生产。

They weren't aggressive, but I yelled and threw a rock in their direction to get them off the trail and away from me, just in case.

他们没有侵略性，但我大喊，并在他们的方向扔石头让他们过的线索，远离我，以防万一。
