Adamite: Ojuela Mine, Mapimí, Mun. de Mapimí, Durango, Mexico

A tiny bit of uranyl ions causes this fluorescence.
Short wave UV
Ambligonite: Tanco Mine, Bernic Lake, Lac-du-Bonnet area, Manitoba, Canada

The cause of this fluorescence is yet unknown.
 
 
Austinite: Gold Hill Mine, Gold Hill, Gold Hill District, Deep Creek Mts, Tooele Co., Utah, USA

The green fluorescence is caused by a litlle uranyl.
White light and short wave UV
Autunite: TL, near Autun,  Saône-et-Loire, Burgundy, France.

The fluorescence is intrinsic. Many uranyl minerals fluoresce yellow to green. A fairly large number of them do that only when they are cooled to cryogenic temperatures. Autunite is one of the brightest fluorescent minerals.
White light and long wave UV
 
Short wave UV
Apatite in Jumillaite: Jumilla, Murcia, Spain

Jumillaite is not a mineral, it is a mixture of calcite, analcime, leucite and other hydrothermally formed minerals in the volcanic rock of Jumilla. This mixture fluoresces white to very light sky blue. The apatite fluoresces an attractive orange-pink due to the the presence of numerous elements from the lanthanides (rare earth elements).
 
Apatitet: Morro Velho mine, Nova Lima, Iron Quadrangle, Minas Gerais, Brazil

Fluorescence due to presence of rare earth elements.
 
 
Apatite: Medina, Jequitinhonha vallei, Minas Gerais, Brazil

Fluorescence due to presence of divalent manganese and rare earths that replace calcium.

Apatite: Golconda mine, Golconda district, Coroaci, Doce valley, Minas Gerais, Brazil

This apatite crystal shows different fluorescent colors depending on the UV wavelength it's bombarded with. This is because different activators only react to specific excitation energies. The crystal is between 2 and 3 mm wide.
Apatite MSH normal light
Apatite MSH long wave UV
Apatite MSH Midrange UV
Apatite MSH SW-UV
 
Tyuyamunite:
Margaritas No. 1 Mine, Sierra Peña Blanca, Peña Blanca District, Mun. de Aldama, Chihuahua, Mexico

One of many yellowish green fluorescing minerals. See spectra for details.
Halogen light and 405 nm violet laser resp.
 
 
Wavelliet:

Kielce District, Świętokrzyskie Mts (Holy Cross Mts), Świętokrzyskie, Poland

Donkerbruin gebroken sferisch aggregaat op witte kwarts. De bruine kleur is allicht afkomstig van ingesloten teer en ander organisch materiaal. Datzelfde materiaal veroorzaakt de fluorescentie.
Halogen light and 405 nm violet laser resp.
