The phosphor absorbs some of the blue light and is "pumped" into an excited state.
It is the phosphor coating, not the mercury vapour itself, that produces the fluorescence effect-and hence the visible light.
Uses: Widely used in high-pressure sodium lamps and ceramic metal halide lamp LED light tube manufacturing and ceramic phosphor, luminescent materials production.
This strikes the phosphor on the glass walls and makes it glow brightly.
The paper discusses on the concept of the phosphorprocess, the theory and influence factors of forming phosphor-film and the effect of quality of phosphor-film on the extension of steel-jar.
Due to the high lumens efficiency, good color reproduction characteristics of single matrix white phosphor, the research on it has great significance.
LED substrates issued partially phosphor-ray absorption, the other part of Blu-ray and issued yellow phosphor mixture can be too white.
Dreams haven't different between distingue and nidering, it's the phosphor in our heart which to direct our advance and direction.
Through analyze, we consider the P-N junction temperature, the concentration of phosphor, the thickness of the coating as the main reason for these electric-light-color parameters changes.
The bulb's 10 diodes, each with a yellow phosphor, sit along a halo of aluminum fingers.
There's still time, the sun just single phosphor.
Fluorescent lights use electricity to excite mercury vapour. This produces ultraviolet light that causes a phosphor coating inside the bulb to glow.
In the process of fabricating a PDP, phosphor undergo the process of paste preparation, drying, sintering and aging etc.
The atom at the tip of the chain emitted electrons onto a surrounding phosphor screen, rendering an image of the electron cloud around the nucleus.
The influence of super absorbent resin on nitrogen, phosphor and potassium in soil were studied.
The plant of growth needs three kinds of elements : nitrogen, phosphor and potassium.
