Low-temperature synthesis of NaRE(WO 4 ) 2 films via anion exchange from layered rare-earth hydroxides (LRHs) films, phase/morphology evolution and photoluminescence

Films of alkaline lanthanide tungstates, NaRE(WO 4 ) 2 (RE = La–Ho, and Y), were hydrothermally synthesized via an anion exchange using electrodeposited layered rare-earth hydroxide (RE 2 (OH) 5 NO 3 · n H 2 O) films as precursor templates in the presence of excess Na 2 WO 4 at pH ∼ 10 and 100 °C, w...
