The effect of temperature on phosphorescence

Click For Summary
Increasing temperature is believed to decrease the lifetime of phosphorescence, though further explanation is not provided. A Google search using the specific problem statement yielded a relevant article from Nature as the second result, which may contain the needed information. The discussion indicates that the inquiry is related to homework, prompting a suggestion to move the thread to a general technical forum if it's not school-related. Participants express interest in verifying the search results and finding answers. The Nature article is recommended for further reading to clarify the effects of temperature on phosphorescence.

Homework Statement
What effect does heat have on a substance with phosphorescence properties?
Relevant Equations
...
I had read somewhere that as the temperature increases, its lifetime decreases. But there was no further explanation. Of course, I don't know if it's true yet.

I did a Google search using your Problem Statement ('What effect does heat have on a substance with phosphorescence properties?'), and the 2nd hit gave the direct answer. Can you try that same search?

Also, is this really a schoolwork question or just something you were wondering about? I can move your thread to the general technical forums if it's not for schoolwork.

Did Google really give a direct answer?! I tried but failed. I'd better try again.
No, this is a homework.:smile:

Thread 'Bernoulli vs real life experiment'

If have close pipe system with water inside pressurized at P1= 200 000Pa absolute, density 1000kg/m3, wider pipe diameter=2cm, contraction pipe diameter=1.49cm, that is contraction area ratio A1/A2=1.8 a) If water is stationary(pump OFF) and if I drill a hole anywhere at pipe, water will leak out, because pressure(200kPa) inside is higher than atmospheric pressure (101 325Pa). b)If I turn on pump and water start flowing with with v1=10m/s in A1 wider section, from Bernoulli equation I...
