摘要: Abstract LnNbO4:Er3+ (Ln = Lu, Y, Gd) phosphors were prepared through a conventional solid-state reaction method. The phase purity of the samples was characterized by X-ray diffraction (XRD). A comparative study spectral and temperature sensing properties presented. excitation spectra show strong band in region 200–350 nm coming from NbO44−, thus indicating efficient energy transfer host to Er3+. From dependence upconversion (UC) luminescence on laser diode working current, it confirmed that 2- 3-photon processes respectively responsible for both green red UC emissions under 980 1550 nm excitations. compared individual 1550 nm. It found independent wavelength, but LuNbO4:Er3+ yielded highest intensity maximum sensitivity.
