Multicolour tuning of different RE ion doped CaMoO4 nanoparticles by single wavelength excitation

The role of the Tm3+ concentration on CaMoO4 properties processed by microwave hydrothermal under stirring condition

“…The CaMoO 4 :Tm 3+ UV‐vis absorbance spectra in the range between 200 and 800 nm are shown in Figure 5. One can observe a broadband with maximum intensity around 260 nm, assigned to the electronic transitions of the [ MoO 4 ] 2− complex 28,71,72 . The bands related to the 4 f n intraconfigurational transitions of the Tm 3+ ion occur between 350 and 800 nm.…”

The results show that the intensity of these bands increases with the increment of the dopant content.…”

“…[19][20][21][22] Several contributions about the properties of CaMoO 4 doped with rare-earth ions are published in the literature. [23][24][25][26][27][28] In particular, the thulium (Tm 3+ )based compounds have potential applications in several technological fields such as telecommunications, medicine, atmospheric sensing, Doppler radar for wind sensor, and near infrared (NIR) phosphors and lasers. There are reports in the literature that Tm 3+ ions exhibit bands emission in the VIS-NIR range.…”
