can we relate the photo luminescence with BH curve of nanomaterial.
Your survey can be simplified. Interrelated magnetic and photoluminescent properties of the material?
Any magnetic material will produce a magnetic field itself which depends on the degree of alignment of magnetic domains in the material set up by orbital and spinning electrons.
Photoluminescence includes fluorescence and phosphorescence. In fluorescence the energy transitions do not involve a change in electron spin, on the other hand phosphorescence involves a change in electron spin and is therefore much slower than the fluorescence process.
Therefore, magnetic and phosphorescent properties of nanomaterials are interrelated due to the electron spin.
Best regards.
No. By BH curve I assume that you mean the hysteresis loop of a ferromagnetic material. This curve is mainly proportional to the magnetic anisotropy of the material or what is the same to spin-orbit interaction (relativistic electronic velocities) and this doesn't depend of the forbiden states of an electronic decay, which is in fact the luminiscence effect. Summarizing, the ferromagnetic phases and the luminiscence are quite separated phenomena which do not depend of the size.
I hope this helps.
As the paramagnetic properties depend on the number of unpaired electrons, the photoluminiscence also depends on the easily excitable unpaired electrons.
