Discovery of novel multifunctional fluorescent materials are of great concern to the development of disciplinary crossing and integration. In this work, we prepared a broad-band Eu3+-activated Lu2MoO6 multifunctional material for potential warm white light-emitting diodes (w-LEDs) and temperature sensor applications. Lu1.9MoO6:0.1Eu(3+) phosphor was synthesized by high-temperature solid-state reaction method, and the structure characterization was investigated for the first time. The excitation spectrum of this phosphor exhibits the intense broad band ranging from 250 nm to 440 nm assigned to the O-2 - Mo6+ charge transfer band (CTB) transition, and a strong red emission centered at 610 nm corresponding to the D-5(0) -> F-7(2) transition of Eu3+ ions were detected under 365 nm excitation. Importantly, warm white light composite material was hybridized via blending commercial green, blue and the present red phosphors, which under 365 nm excitation exhibited a high color rendering index (CRI) of 78 at a correlated color temperature of 4271 K with CIE coordinates of x = 0.351, y = 0.308. Furthermore, a strong temperature sensitization phenomenon was found, where the results show that the emission intensities and chromaticity coordinates are sensitive to the temperature, which can provide guidance for the potential application in temperature sensing.
