Study of luminescence, color and paramagnetic centers properties of albite 

Cano, Nilo Francisco [UNIFESP]; Santos, Lara H. E. dos; Chubaci, Jose F. D.; Watanabe, Shigueo (Elsevier B.V., 2015-02-25)
A sample of natural albite, NaAlSi3O8, from the state of Minas Gerais, Brazil, has been investigated. the mineral is a solid solution of K-feldspar (4600 ppm - K) and Ca-feldspar (1100 ppm - Ca). the TL spectra of natural ...

Dating and determination of firing temperature of ancient potteries from São Paulo II archaeological site, Brazil by TL and EPR techniques 

Cano, Nilo Francisco [UNIFESP]; Ribeiro, Rogerio B.; Munita, Casimiro S.; Watanabe, Shigueo; Neves, Eduardo G.; Tamanaha, Eduardo K. (Elsevier B.V., 2015-05-01)
Pottery fragments from São Paulo II (SPII) archaeological site were dated by means of thermoluminescence (TL) and electron paramagnetic resonance (EPR). EPR was used to study the firing temperature using the iron signal ...

Centers responsible for the TL peaks of willemite mineral estimated by EPR analysis 

Rao, T. K. Gundu; Cano, Nilo F. [UNIFESP]; Silva-Carrera, Betzabel N.; Ferreira, Reinaldo M.; Javier-Ccallata, Henry S.; Watanabe, Shigueo (Elsevier Science Bv, 2016)
The mineral willemite (Zn2SiO4) exhibits five thermoluminescence (TL) peaks approximately at 160, 225, 260, 310 and 400 degrees C. Electron paramagnetic resonance (EPR) studies were carried out to study the defect centers ...

High- and very-high-dose dosimetry using silicate minerals 

Watanabe, Shigueo; Cano, Nilo Francisco [UNIFESP]; Carmo, Lucas S.; Barbosa, Renata de Faria [UNIFESP]; Chubaci, Jose F. D. (Elsevier B.V., 2015-01-01)
In the present study, certain natural silicate minerals such as aquamarine (AB), morganite (PB), goshenite (WB), white jadeite (JW), green jadeite (JG), pink tourmaline (PT) and two varieties of jadeite-like quartz, denoted ...

Thermoluminescence in Lapis Lazuli crystal: Glow peaks and their connection with F-centers estimated by ESR analysis 

Silva-Carrera, Noemi B.; Cano, Nilo F. [UNIFESP]; Gundu Rao, T. K.; Ayala-Arenas, Jorge S.; Watanabe, Shigueo (Elsevier Science Bv, 2017)
The mineral Lapis Lazuli exhibits three thermoluminescence (TL) peaks approximately at 140, 260 and 370 degrees C. The TL intensity of the three peaks grows with radiation dose and it saturates only beyond 9 kGy. Electron ...
