“…This result indicates that the mechanism of PersP effect should be highly associated with the thermal release of electrons in traps (V cc o ) just like PersL. 20,22,[31][32][33] Cycled runs of the PersP experiments have been also tested using the black peony-like BiOCl sample aer visible light irradiation. The PersP ability doesn't show a decline even aer 10 cycles as shown in Fig.…”

“…According to some references on PersL, the traps with appropriate depths are very signicant for the PersL properties of phosphors, and the traps in most efficient PersL phosphors are highly associated with the intrinsic oxygen vacancies (V cc o ). [17][18][19][20][21][22] On the other hand, according to some references on photocatalysis, the oxygen vacancies can be generally induced in BiOCl by reduction method using Fe, 23 nitrogen doping 24 or UV light irradiation. 3,25 The BiOCl photocatalyst with rich oxygen vacancies shows black body, and it exhibits high photocatalytic ability under visible light irradiation.…”

“…Detection of the environment of Sm 3+ ion sites by Eu 3+ ions as probes.-The ionic radii of Gd 3+ 1 (CN = 9), Gd 3+ 2 (CN = 7), Si 4+ (CN = 4), and Sm 3+ are 110.7 pm, 100 pm, 26 pm and 96 pm, 14,15 respectively. Due to their different valence states and ionic radii, we propose that Sm 3+ ions will replace the Gd 3+ sites (both Gd1 and Gd2) in Gd 9.33 (SiO 4 ) 6 O 2 host matrix randomly.…”

“…17,18 The ionic radius of Eu 3+ ion is 96 pm, which is nearly the same as that of Sm 3+ ion. 14 Thus, we can take Eu 3+ ions as probes to detect the environment of Sm 3+ ion sites. The emission spectrum (λ ex = 273 nm) of Gd 9.33 (SiO 4 ) 6 O 2 :1.5%Eu 3+ was presented in Fig.…”

“…Alkaline earth orthostannates have recently received more attention as a new phosphor material, owing to their stable crystalline nature and high physical and chemical stability [19]. Rare earth metals and transition metals were used to control the photoluminescence properties of the host phosphor material that are used in flat panel displays, field emission displays, and electroluminescence devices [20,21]. Detailed electrical properties of Ba2SnO4 have already been described in the literature; two types of conduction mechanisms have been found to be operative within the investigated temperature range, assigned to electronic conduction at low temperatures and ionic conduction at higher temperatures [15].…”
