Naphtalene solid state Quantum Yield

AI Thread Summary
The discussion centers on the absolute quantum yield of naphthalene as measured with an integrating sphere. The original poster seeks reference values to calibrate their sphere for UV emissions, specifically looking for published data to compare with their measurements. They mention that their integrating sphere has a correcting function for wavelengths starting at 330 nm but need to extend this to cover 310 nm. The conversation highlights the importance of accurate calibration for quantum yield measurements and invites suggestions on creating a correcting function for the integrating sphere. A humorous remark about naphthalene spheres being used for moth prevention adds a light-hearted touch to the technical inquiry.

Hi guys,
first of all I want to say that this forum saved me several and several times and I love it.
I have a question for you related to absolute quantum yield of naphthalene determined with an integrating sphere. Do you have an idea how much should be? COuld you pass me a reference paper (that I am not able to find).
The purpose is that I need to calibrate my sphere for emissions closer to the UV region and I want to compare a published value with a measured one and see how much deviate from it.
Thanks a lot

I use naphtalene spheres to prevent my clothes being eaten by moths. However, they tend to disintegrate instead of integrate.:smile:
Seriously, a more detailed description about what kind of measurement you are talking about could be helpful.
 
Ok I go deeper.
Basically we have just received an integrating sphere to determine absolute values of quantum yields. The sphere comes with a correcting function that takes in count the behaviour of the reflecting material through the different wavelengths. However the correcting functions starts from 330 nm and covers all the visible spectra.
Since I need to cover 20 nm more (from 310 to 330) in the correcting function of the sphere, I was thinking to use naphthalene in order to determine the quantum yield and compare it with the literature one and see how far we are.
However if you have an idea how to create a correcting function for an integrating sphere, do not hesitate to tell me because I am going mental with this!

Thanks a lot in advance

Thread 'How to make Sodium Chlorate by Electrolysis of salt water?'

I have a power supply for electrolysis of salt water brine, variable 3v to 6v up to 30 amps. Cathode is stainless steel, anode is carbon rods. Carbon rod surface area 42" sq. the Stainless steel cathode should be 21" sq. Salt is pure 100% salt dissolved into distilled water. I have been making saturated salt wrong. Today I learn saturated salt is, dissolve pure salt into 150°f water cool to 100°f pour into the 2 gallon brine tank. I find conflicting information about brine tank...
