Combustion Synthesis and Luminescent Properties of Eu3+-Activated Cheap Red
Phosphors. — Red phosphors LnMAlO4 (Ln: La, Y; M: Ca, Sr) doped with Eu3+ are
32- 009 synthesized by rapidly heating aqueous solutions containing stoichiometric amounts
of the corresponding metal nitrates, NH4NO 3, and urea at 525 °C. The samples are characterized by powder XRD and luminescence spectroscopy. All the Eu3+-activated compounds exhibit red emission in the 605—625 nm region under 254 nm irradiation. —
