If you don't have an integration sphere, you'll find the quantum yield by a comparsion of the emission and absorption properties of your sample and some standard compound, see e.g. http://www.horiba.com/fileadmin/uploads/Scientific/Documents/Fluorescence/quantumyieldstrad.pdf
For solution samples, you can measure either by integration sphere or by comparison with a reference. For quantum yield calculation using the reference method you will require both absorption spectrum and emission spectrum of both the sample and reference and the refractive indices of solvents in which the quantum yield is being measured as given above.
For solid samples, see this link
