制出了稀土硫氧化物薄膜,这种薄膜本征阴极射线发光效率与同样的粉末状材料相等。这些薄膜可承受电子束装置的最大功率密度7W/mm~2,而不致烧伤或强度达到饱和。用12—KV阴极射线激发铽(Tb)激活的硫氧化镧薄膜,测得最高亮度,4×10~4呎朗伯是受到激发设备条件的限制的、做出了以Eu,Tb,和Tm激活的一种硫氧化镧多层薄膜,其发光颜色随电压而变化。 Produced a rare earth oxide film of sulfur oxide, this film intrinsic cathode ray luminous efficiency equal to the same powdery material. These films can withstand the maximum power density of electron beam devices 7W / mm ~ 2, without burns or saturation. Tb-activated lanthanum oxysulfate film was excited by 12-KV cathode ray and the maximum brightness was measured. The 4 × 10 ~ 4 foot Lambert was limited by the conditions of the excitation device. Eu- Activation of a multi-layered lanthanum oxysulfide film, the emission color changes with voltage.
