What does 999 mean on jewelry?
These numbers are purity marks stamped into metal, they represent the number of parts out of 1000 of pure metal in the piece. 925 is the purity mark for sterling silver, which is traditionally 92.5% pure silver and 7.5% copper. 999 on the other hand is what’s known as fine silver, 99.9% pure silver.
What does 333 mean on jewelry?

What is the difference between fluorescence and phosphorescent materials?
Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the radiation energy and reemits it for a much longer time after the radiation source is removed.
What is phosphorescence in quantum mechanics?
Phosphorescence. Phosphorescence is a type of photoluminescence related to fluorescence. Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with ” forbidden ” energy state transitions in quantum mechanics.
How does the process of phosphorescence work?
How Phosphorescence Works. Phosphorescent materials may appear to glow for several seconds up to a couple of days after the light has been turned off. The reason phosphorescence lasts longer than fluorescence is because the excited electrons jump to a higher energy level than for fluorescence.
What are spin-allowed transitions in phosphorescence?
Since during all those transitions the electron spin is kept the same, they are described as spin-allowed [6,7,10]. For phosphorescence, things are a bit different (see Fig. 4). There are again an S0 ground state and the two excited states, S1 and S2.
