Herein, a dual mode luminescence behavior of rare earth doped/codoped CaMoO4:(Eu3+, Eu3+/Yb3+) phosphors synthesized by hydrothermal method are presented. The structural analysis and surface morphology were investigated by X-ray diffraction, field emission scanning electron microscopy and Fourier transform infrared spectroscopy techniques. The optical properties were studied through UV–vis diffuse reflectance spectroscopy, photoluminescence (PL) and lifetime measurements. The PL excitation spectra of Eu3+ doped CaMoO4 phosphors were recorded at different excitation wavelengths such as 250, 270, 300, 394 nm wavelengths. The down-shifting PL emission spectra of phosphors were recorded at optimized 250 nm excitation wavelength. In addition, emission was also recorded for Eu3+/Yb3+ codoped CaMoO4 phosphor after an excitation wavelength 980 nm through up-conversion process. The phosphors show hypersensitive red emission (5D0 → 7F2) through down-shifting as well as up-conversion processes. The red color was visualized by using commission international de L’Eclairage (CIE) chromaticity diagram. Thus, the obtained results show that dual-mode red emitting phosphors may be used as spectral converter in solar cells.
