Optical studies in Er3+ doped BaMoO4 downconverting phosphor for blue LEDs

Erbium ion (Er3+) doped BaMoO4 phosphor has been synthesized via co-precipitation technique. Phase formation of the prepared phosphor has been recognized by powder X-ray diffraction analysis. The photoluminescence emission spectrum has been recorded in 400-800nm wavelength range under 380nm excitation. The observed photoluminescence peaks are explained with the help of energy level structure. The prepared phosphor seems capable to produce efficient blue colour emission which can be useful for making blue light emitting diodes (LEDs).
